Or get a 16650 or 16750 based card. I have a dual 16C650 card in my dial-in server, running two Impact IQ ISDN adapters at 115,200 bps, and have had no problems whatsoever. One of these days I'm going to figure out how to crank them up to 230,400 bps. If this is an internal modem, rip it out of your machine and give it to somebody running Winblows who doesn't expect much in the way of throughput. Most internal modems have a flawed pseudo-16550 UART. -- "Where am I, and what am I doing in this handbasket?"
