Hi

here's another UDF for the serial port. It is very similar to CommAPI using kernel32.dll, but all code is packed into a single file without any dependencies, not even using WinAPI.au3. It differs from existing UDF that it doesn't allow a timeout when reading, instead it always returns immediately, either with the requested amount ob bytes read or with a failure status. And of course there is a function provided to query the amount of available bytes in the receive buffer. The reason behind this design decision: You can do 1000 other things in the main loop while checking from time to time if enough data bytes arrived. There's no point to block the program waiting for the serial port.

It is currently a work-in-progress, as I didn't test all functions yet. The code was developed and tested on Windows 7 64 bit.  The ComUDF-Tests.au3 shows some tests and basic usage of the UDF. Maybe there's no reason to use this UDF, given the existence of the others UDFs, but I did it to get to know DllCall better - I use structs no only to pass but also to get data back (I don't use the array returned by DllCall to read that data, unless required). You're welcome to test it on older and newer Windows versions.

Here's a list of the implemented functions:

; _ComListPorts
; _ComOpenPort
; _ComSetTimeouts
; _ComClosePort
;
; _ComSetBreak
; _ComClearBreak
; _ComGetInputcount
; _ComGetOutputcount
; _ComClearOutputBuffer
; _ComClearInputBuffer
;
; _ComSendByte
; _ComReadByte
; _ComSendBinary
; _ComReadBinary
;
; _ComSendChar
; _ComReadChar
; _ComSendCharArray
; _ComReadCharArray
; _ComSendString
; _ComReadString
;
; __ComClearCommError
; __PurgeComm

Hello MazeM,

Thank you for your contribution! I've discovered a couple of issues with ComUDF at the moment:

1) The following code fails to properly recognize 2 and 3-digit COM ports on both 1x Win7 64-bit PC and 5x Win10 64-bit laptops. Anything past the first digit is simply ignored (odd because the code seems fine to me...).

;extract $comPort from $defs
   $comPort = StringLeft($def, 4)      ;"com1".."com9" (com plus 1st digit)
   If IsNumber(StringMid($def, 5)) Then ;"com10".."com99" (2nd digit)
      $comPort &= StringMid($def, 5)
      If IsNumber(StringMid($def, 6)) Then ;"com100".."com256" (3rd digit)
         $comPort &= StringMid($def, 6)
      EndIf
   EndIf

2) Windows uses UNC paths for anything above COM9 (https://support.microsoft.com/en-us/help/115831/howto-specify-serial-ports-larger-than-com9), so any 2 and 3-digit strings generated by the code above would be invalid. It is recommended to append "\\.\" to every COM port number.

 

Fortunately, the following code was tested on the above systems and will remedy the issues above completely by a) utilizing StringIsDigit/StringTrimLeft instead of IsNumber/StringMid and B) appending a prefix of "\\.\" to any COM port between 1 and 256.

;extract $comPort from $defs
   $comPort = "\\.\" & StringLeft($def, 4)      ;"com1".."com9" (com plus 1st digit)
   If StringIsDigit(StringLeft(StringTrimLeft($def, 4), 1)) Then ;"com10".."com99" (2nd digit)
      $comPort &= StringLeft(StringTrimLeft($def, 4), 1)
      If StringIsDigit(StringLeft(StringTrimLeft($def, 5), 1)) Then ;"com100".."com256" (3rd digit)
         $comPort &= StringLeft(StringTrimLeft($def, 5), 1)
      EndIf
   EndIf

I would appreciate some help. When i try to use  _ComListPorts() to get a list of  com ports in an array it always comes up blank. What am i doing wrong? In fact the Array display does not even open up a window. The script end without an error. 

#include <Array.au3>
#include <comUDF.au3>

Local $ports = _ComListPorts()
_ArrayDisplay($ports)

 Can anyone help?

Hi There,

I'm trying to read from my Com port but I can't.

I'm able to send it successfully and i know that my com port gets the characters (tried it with TeraTerm) but when i try to read the COM port with Auto it it just gives me 0.

Following is my code to read the Com port

Func    FUNC_021_Read_From_Com($i_com_num)

   Local $ports = _ComListPorts()
   Local $ports_arry = _ComListPorts()          ;an array with com ports
   Local $s_ComPort='COM' & $i_com_num          ;a com port, e.g. COM1
   Local $s_Def='baud=57600 data=8 parity=n stop=1' 
   Local $h_ComPort ;serial port handle
   Local $s_Info = 'cbOutQue'
   Local $i_num_chars = 16
   Local $b_rtn
   Local $i_Length
   Local $i_comp
   Local $s_Readstr


   $h_ComPort = _ComOpenPort($s_ComPort & $s_Def)

   if ($h_ComPort <> 0) Then

      __PurgeComm($h_ComPort, '0x000F')
      __ComClearCommError($h_ComPort,$s_Info)


      Sleep(5000)
      $s_Readstr = _ComReadString($h_ComPort, 26, 2)    
      MsgBox($MB_OK," Programming Serial Number!"," This is What I Get: " & $s_Readstr) ; I Get 0

      _ComClosePort($h_ComPort)
   
   EndIf

EndFunc

Any suggestion is appreciated

Thank you

        * Change variables naming to fit AutoIt convention
        * Fixed DllCall return check
        * changed function name __PurgeComm >> __COM_Purge
        * fixed many function to start it works
   V2.94
   Danyfirex 25/09/2020
        * small fixes
   V2.95
   Danyfirex 28/09/2020
        * modified function _COM_SendString - now it use _COM_SendBinary instead _COM_SendCharArray
   V2.96

But as so far we not publish our modified version so your mod will be about V2.97 if you do not have any objections.
I hope we post this in next few days toogether with your fix.


EDIT 1:
As I said we not publish our modified version, because we are working on some other project which is realted to this UDF.
I hope this other project will also be published here but it need times.

Unlimited thanks to creator of this UDF and other who took part in this!!!


Can I asked question and also suggest one thing (in case of positive answer on this question)?:
Does this UDF involves that you can connect to several COM ports in one application? If it does, there is a little problem. Let me explain more detaily:
For example, I have two COM ports (COM1 and COM2) in my system and I want to use them both at one time in my application. So I do next:
1) open COM1 port using function and according definition:     $hCom1Open = _COM_OpenPort("COM1 baud=9600 parity=N data=8 stop=1")
2) open COM2 port using:     $hCom2Open =  _COM_OpenPort("COM2 baud=9600 parity=N data=8 stop=1")
3) then I can use both my handles of opened ports as I need (receive and send data)
4) now I need to close one port (for example COM2). I do it successfully with function _COM_ClosePort($hCom2Open)
5) and now I can do nothing with opened port $hCom1Open, including receiving, send data and also it is impossible to close the handle:     _COM_ClosePort($hCom1Open) returns -1
As I see, this all because of global variable $__g_hCOMUDF_Kernel32 which is get its value during DllCall when opening port:     $__g_hCOMUDF_Kernel32 = DllOpen('kernel32.dll').
When you close port, the common handle ( $__g_hCOMUDF_Kernel32) of DllCall also terminated. This seen from function _COM_ClosePort():     DllClose($__g_hCOMUDF_Kernel32).

 

So my suggestion is to add a handles counter of each opened port. For example, to do it this way:
1) add a variable near global variables definition:     Global $__g_hCOMUDF_Kernel32, $i_h_Count = 0
2) in _COM_OpenPort replace line of __g_hCOMUDF_Kernel32 defiinition:     If $i_h_Count = 0 Then $__g_hCOMUDF_Kernel32 = DllOpen('kernel32.dll')
3) before the last line (Return value) in _COM_OpenPort function add this line:     $i_h_Count = $i_h_Count + 1
4) in function _COM_ClosePort replace line of DllClose by two lines:
$i_h_Count = $i_h_Count - 1
If i_h_Count = 0 Then DllClose($__g_hCOMUDF_Kernel32)

After those steps (as I tried to do in my app) you can open several COM ports and work with them without any problems even if one or more will be closed later.


Please, I will be very appreciated if you will comment my question and my suggestion. As for me, understanding calls of CreateFile is not so easy. That's why I'm not sure if I correctly using this UDF and work with serial ports at all. Especially due to never worked in C++. My experience in programming started and continues only in AutoIt.

Hello @Filipp_G, I'm using this library pretty often, it is really helpful. I just want to say, if you already solved the problem, why not share what you have? Just increase the version number, put your comments on the beginning of the file and upload it. This way anyone can improve it.

Hello, @Chuckero! Thanks for reply. Yes, it's not a problem to do this. But just one thing to ask: does everyone mind if I delete the Note section from _COM_SendString function description, which is under the spoiler?:

Spoiler

; ===============================================================================================================================
; Function Name:       _COM_SendString($hComPort, $string, $encoding=1)
; Description:        Sends data
; Parameters:         $hComPort - serial port handle (as returned by _COM_OpenPort)
;                    $string   - the string to write
;                    $encoding - 1=ANSI (default), 2=UTF-8
; Returns:          on success returns the number of bytes written
;                   on error returns -1 and sets @error to 1
; Note:
; If there are less bytes than requested in the input buffer it returns 0
; ===============================================================================================================================

As I think, this comment is not suitable for this function, because the send operation is not depend of input buffer.

Yes, that comment doesn't seem to make sense.

      Computer Plucker is a fork and a "restoration" of Computer stats utility by @Rogue5099 (link)
      You can obtain various data about local machine, as from the screenshot.

      But my goal is not (only) to provide another PC stats tool, but to develop a very basic remote inventory tool, like (a small subset of) the abandoned Spiceworks or the Microsoft SCCM.
      So this script can be deployed on a machine as a standalone executable (yes you need only ONE file to distribute) , and launching the .EXE it installs itself to a folder (es. c:\autoit\computerplucker)
      In tools menù you can set two tasks and not only
      one for creating every week a file.ini with all the data of the machine. another one  for creating every week a file.ini with all the data of the machine PLUS uploading a CRYPTED record of the machine in a free mysql DB online For my needs, I am  deploying the .exe and schedule the second task, uploading data one time a week.
      In tools menù you will find also commands for:
      manual creating the .ini data file  to upload the data in crypted records to upload the data in clear text records (for testing..) total uninstall of ComputerPlucker, with a simple security code. many other tasks in not so logical order.. next version I have to tidy the menù... So my plan is to deploy this on my machines, and have the data in a online DB, this DB will be for me only a "cache" for data records to be downloaded (and deleted) by another script.
      As today the account of this TEST DB is embedded in code, using the "File to Base64 String' Code Generator" by @UEZ (used also for embedding icons and XML task definitions)
          Local $mysqlhost = "sql11.freemysqlhosting.net"
          Local $mysqlport = "3306"
          Local $mysqldb = "sql11403701"
          Local $mysqluser = "sql11403701"
          Local $mysqlpsw = "QtL7T9U5GV"
      The DB is one table of 30 mysql tinytext fields... very simple indeed...
      You can try to upload data to this DB and access (phpmyadmin or a random mysql browser app) to see the results.
      Or you can use my ComputerPluckerDBbrowser (see at the end of this post) a script to collect and manage the data.

      PRIVACY warning: you are uploading data of your PC account and PC data, test as your risk (or test in another account...)
       
      I also created a small post in a blog for not so geek friends, and I have a more advanced version of the data browser, you can have more info lookin' here. 😀
      Attached you will find the code, and all the necessary includes are at this >link<.
      ComputerPlucker.EXE is downloadable >HERE<

      Hi All,
      I didn't know where to put this; my apologies if this is the wrong location.
      When you plug a Samsung mobile device (phone, tablet, etc.) into the USB of a Windows PC, you can right-click the device in My Computer and select Properties. Here, it will show you the correct serial number of the device. Clearly Windows doesn't use adb to get the SN so I'm stuck at how to get the SN without adb and where the device doesn't have a drive letter assigned to it.
      When I last picked this up, I tried seemingly everything I could from wmi(?) and winmgmts(?) but either it's hidden cloak-and-dagger style or I can't see the forest for the trees...
      Does anyone know what API Windows uses when getting the serial number of a device Windows calls a Portable Media Player?
