Line 1500: Error: The requested action with this object has failed

Complete and utter newb here

I have considerable experience writing 'C' and Assembler but my first steps into AutoIT and it looks good.

However I have an immediate problem

I am using a basic .au3, (not BASIC), program which monitors input from a serial USB port donated by a kind fellow for me to improve.

I have installed AutoIT3 and ScITe 3.3.

Load the program and Compile or Bulid it then try to run the exe I get:

Last line number in file is 235 !

RTFM (briefly) but don't see any clues.

Welcome to AutoIt and the forum!

Most of the time this error message is caused by a COM error.

I suggest to use a COM error handler to get detailed error information.

Function ObjEvent in the help file describes how to do.

welcome to the AutoIt forum,

run your code directly from SciTe (without compiling), you will see much more details and specific location of the error.

do not be alarmed by the line number, you will easily see where it comes from.

Thanks guys.

Nice trick. Didn't know we can run the script directly from ScITe

Came up with this

F:\Program Files\AutoIt3\Chrony\testbox.au3 (18) : ==> The requested action with this object has failed.:

$MsComm.PortOpen = 1

$MsComm.PortOpen = 1^ ERROR

So from the code above

$MsComm = ObjCreate("MSCOMMLib.MsComm.1")

$MsComm.CommPort = 4

$MsComm.Settings = "4800,N,8,1"

$MsComm.Handshaking = 1

$MsComm.InBufferSize = 1024

$MsComm.InputLen = 1

;Connect

It's clear I don't have the respective COM4 on this machine.

Thanks for the tips.  Now I can forge ahead
