I am trying to add 2 more serial ports to my SuSE 6.1 installation.
ttyS0 and ttyS1 (irq 4 & 3) work fine, but ttyS2 and ttyS3 (on irq 11
and 12) only pass characters at a VERy slow rate. I tried SETSERIAL but
it doesn't seem to help.
What' the trick? Do I need to recompile the kernal?
Also, what advice do you have for mutliple port serial cards? I'd like
to have a few modems, as well as packet radio TNCs on the machine.
