I have a TurboColor running System 2.2 I use the SupraFax 14.4K with the hardware handshaking cable. I originally had problems with IComm and TIP talking reliable at 38K. I received transmit and receive errors on my modem with lousy recovery. However, I had a temporary fix: renice Yep, it worked. Just giving it a higher priority was enough to get the data when it interrupted. However, I've upgraded my system RAM from 16Megs to 32Megs. Now that my machine isn't having to swap/page memory, it doesn't miss those interrupts for the serial line. Everything is peachy now. :-) ++jerry(); // jscoggin@netcom.netcom.com
