RE: [Dev-C++] Serial Communication

[Alex C. <al...@ca...>]

Thank  for info.I understand that but:

Direct hardware access in 32-bit Windows is generally not allowed. While it
can be done in the Win9x OS by using inline assembly, this is generally
discouraged as this technique is not supported under WinNT. The hardware
port communication family of functions, such as inportb, inpw, outportb and
outpw are now deprecated and are no longer supported. Is there some way  to
use Win32 API CreateFile and the Win32 communications functions under
Dev-C++?
Thanks in advance

Alex Cosic

You might want to look at this sample code from Planet Source Code It uses
Win32 API functions to access the comm ports.
Class for serial port access under Windows NT.

Re: [Dev-C++] Serial Communication

[Bolek V. <vr...@pa...>]

I had written a non-overlapped serial communication in C++ some time
ago. It uses Win32 API, but it didn't work under Dev-CPP 4.0. It works
under Borland's free C++ compiler 5.5. I guess there is an error in
Dev-CPP (or in my code? - I just read the Win32 API help from Microsoft
and wrote something). It will hang at somewhere at GetCommState in open(
) under DevCPP 4.

I send it to you. It is a part of a much greater work that controls a
scientific device. The device can be controlled with serial port or GPIB
- that's why I created an abstract class TCommunicator. Just changing
the communicator used from TSerialComm to TGPIBComm will make the
program use GPIB instead of serial.

The device reads a command, obeys it and sends a response. The response
always ends with a special char - the end char. No end char means the
response didn't come. So I wait for it to come and then read the
response.
  comm->send( ....);
  comm->wait( ....);
  comm->read( ....);

That's how I use it. TNessyException is a special class of exceptions
defined in the program and errCommError and errMemory mean an error in
communication or error in memory allocation occured. id is device id -
forget it.

The WinAPI functions used are explained in the Microsoft's Win32 API
help file. I think you can download it at Dev-CPP's web site.
