Serial Communication
I am trying to communicate between serial ports. The MSCOMM activex code works, but it is not what I want to use because you need the license and so forth. I have found a few examples on the web, but do any of you know a flawless way to do serial communication (read/write).

Re: Serial Communication
I don't want to use any ActiveX code at all.

Re: Serial Communication
Search in CodeGuru for "serial port". There were answers suggesting this, but somehow they disappeared...
"Programs must be written for people to read, and only incidentally for machines to execute."

Re: Serial Communication
Well...assuming the Windows operating system...
Depending on what you are trying to do take a look at the functions
Code:
BuildCommDCB()
ClearCommError()
CreateFile()
EscapeCommFunction()
GetCommModemStatus()
GetCommState()
GetCommTimeouts()
GetOverlappedResult()
ReadFile()
SetCommMask()
SetCommTimeouts()
WaitCommEvent()
WriteFile()
Additionally, the MSDN provides a detailed article about serial communication in Windows. Open MSDN, choose Index and type "Serial Communications". There are several subitems, choose 'Win32'... (it's also available online).
