I'm using Visual Studio 2003; and I'm linking with SDL, so it's fairly messy what the entry point is.

      • Hi, I'm doing communication over a serial port and I took a library on the internet handling everything. Sadly, I ran into problems when I began to Read from the port.

If I just write on the port, I got no problem
