[parisc-linux] Strange serial behaviour on C160

[Peter Mottram]

I am seeing weird serial behaviour on my C160......

Before upgrading from HP-UX to Linux I had two perfectly functioning
serial ports on my C160. I now appear to have THREE serial ports -
ttyS[0-2].

ttyS0 works perfectly
ttyS1 goes somewhere - not found where yet
ttyS2 goes to my second serial port but does not work at all well. A
simple cat of a file to the device results in the file appearing on a
terminal just a few characters at a time & incredibly slowly. All serial
ports have the same settings & ttyS0 has no problems (I use it for the
console).

I checked a C110 & found no problems there - just 2 perfect serial ports.

Anyone have any ideas?

TIA
