Maurice,
Thank you for answering. Yes, I have the sources, but the application I have to do is intended to run in a PC-DOS 7.0 powered hand computer.
No windows then. So the delphi sources probably won't help much because they probably use calls to windows dll to communicate with the serial line. Unless Turbopower use directly dos or hardware interrupts. In that case djgpp's libc has functions to call interrupts from within protected mode. This is the way bcsio20 works. Impossible to say more without more informations !
