Migration has not been very difficult except for one of the modules that reads/writes from/to serial port (/dev/ttyS* -> COM*). Linux version opens the port (fd = open("/dev/ttyS0") and then use read() and write() to receive and send data. I rewrote open, send and receive functions using bioscom(...). Opening and writing functions work fine, however reading justs gets the last character received by the serial port. I have seen (and test) programs using Win32API/dev-cpp (SetupComm ...) that interact with serial port like a regular file. I'm looking for similar functions with djgpp. Is it possible to read a stream of bytes received by the serial port, not just a single one? Thanks in advance PD: I dont know if pmcom could be a solution. I tried to compile it, but it failed.
