D J, I was wondering if the aeasync library would be easily modifiable for use of the COM3 and COM4 ports?? Is it difficult to program code for COM3 and COM4 due to the shared interrupts with COM1 and COM2?? I know next to nothing about programming the RS-232 on the IBM, but I always notice that most libraries only support COM1 and COM2. Oh well, just curious!
