Hyperterminal Console read characters

7 posts in this topic

Greetings to AutoIt community.

I am using AutoIt v3. My requirement is to automate some activities where hyperterminal is launched and connected to an embedded device through serial COM port. Based on what gets displayed on hyperterminal, some commands need to be typed. This means characters and strings getting displayed in hyperterminal need to be identified and parsed to perform further actions.

I am able to launch hyperterminal and enter characters into the terminal. But I am stuck at reading characters from hyperterminal. Some support in achieving this will be very helpful.

Using CommMG UDF would not be an ideal choice because I think CommMG needs full access of COM port which means hyperterminal cannot be connected to same com port in parallel.

Thanks
Mayur

StdoutRead didn't work? Show a runable (reproducer) script with the issue.

I couldn't achieve what I wanted with StdoutRead( )
Details on how I tested are ..........

Code:

#include <GuiEdit.au3>

Local $iPID = Run("C:\Projects\Utilities\Hyperterminal\hypertrm.exe")
Local $hWnd = WinWaitActive("Connection Description")

ControlSend($hWnd, "Connection Description", "Edit1", "CONSOLE_1")
Send("{TAB}{TAB}{ENTER}")

Local $idCombo = WinWaitActive("Connect To")
Send("{TAB}{ENTER}")
Send("!r")
Send("1")
Send("1") ; Configuring com port conection settings


Send("{ENTER}") ;Reached Terminal screen

Send("{ENTER}")
Send("{ENTER}") ;Login request appears in console
Sleep(2000)
;Local $Console = StdoutRead($iPID)
;Local $Console = StdoutRead($iPID, True, False)
;Local $Console = StdoutRead($iPID, False, False)
;Local $Console = StdoutRead($iPID, False, True)
Local $Console = StdoutRead($iPID, True, True)

MsgBox($MB_SYSTEMMODAL, "Information", "$Console: " & $Console)

When hyperterminal prints "login:" automatically user name should get entered. But the string "login:" is not getting recognized by StdoutRead() as shown in the screenshot.

Hello.

Use PuTTY.EXE instead of hyperterminal for doing your COM1 communication. PuTTY.EXE works fine with StdOutRead()

You must use the parameter opt_flag with one of both:

Quote

$STDOUT_CHILD (0x2) = Provide a handle to the child's STDOUT stream
 $STDERR_MERGED (0x8) = Provides the same handle for STDOUT and STDERR. Implies both $STDOUT_CHILD and $STDERR_CHILD.

, try this script:

#include <GuiEdit.au3>

Local $iPID = Run("C:\Projects\Utilities\Hyperterminal\hypertrm.exe",@SW_SHOW,$STDOUT_CHILD)
if @error Then Exit

Local $hWnd = WinWaitActive("Connection Description")

ControlSend($hWnd, "Connection Description", "Edit1", "CONSOLE_1")
Send("{TAB}{TAB}{ENTER}")

Local $idCombo = WinWaitActive("Connect To")
Send("{TAB}{ENTER}")
Send("!r")
Send("1")
Send("1") ; Configuring com port conection settings


Send("{ENTER}") ;Reached Terminal screen

Send("{ENTER}")
Send("{ENTER}") ;Login request appears in console
Sleep(2000)

Local $Console, $oldcon

While ProcessExists($iPID)
    $Console = StdoutRead($iPID)
    If $Console<>$oldcon Then
        MsgBox($MB_SYSTEMMODAL, "Information", "$Console: " & $Console,5)
        $oldcon=$Console
        $Console=''
    EndIf
WEnd

Dear AutoBert,

I added the missing working directory argument for Run() with value "" after which script executed , but if condition is not becoming TRUE.
