We're running SLIP on a 386SX-16 with 4MB run over a 19.2K V.42bis modem with the serial port locked at 38400. We only get silo overflows when a program starts up. It seems like the wd driver blocks the serial interrupts to long. But I haven't investigated this since I have more important work to do. :-) >It seem to have some impact on the performance >but then I just could be imagening that.

From what I've deduced so far one would have to hack the kernel or buy a faster machine, of course. -- Christoph Badura bad@flatlin.ka.sub.org +49 721 606137 Es genuegt nicht, keine Gedanken zu haben; man muss auch unfaehig sein, sie auszudruecken. - Karl Kraus
