Product    :BC++  5.x

Question:

What command is available for Borland C++ 4.5 to write to a com 
port opened with CreateFile. I need a 32 bit function
to write to the port because the baud rate must be 38400.
I need a simmilar command to TransmitCommChar, but it should 
work with CreateFile and not OpenComm.

Answer:

Look at the Communications section in the Win32 on-line help for
information about ReadFile and WriteFile for serial
communications.
