For info on a PC (DOS) modem connection Andre LaMothe's book the Black Art of 3D Programming contains a detailed explanation on setting up the PC serial port and communicating with the modem. The maximum baud rate is only 2400bps though, for higher transmission speeds you'll need to use one of the standard data compression and error correction schemes. If you search the net you should be able to download a software library containing these modem protocols (I've had no luck yet). To control the psx serial port, you should be able to use the ioctl( ) function in the updated Libps library. I've not been able to get it to work though, perhaps SCEE could give us a few examples ?? Even without ioctl, you can read( ) and write( ) data thru the serial port at 9600 or 115200bps. I've had two playstations chirping happily to each other via a link cable. I hope this helps, if you need any info on the PC serial port or modem commands I can mail it to you, Pete.
