>Description:
When I add the following lines to the kernel config file, the PCMCIA
serial port works (sio2) but the onboard serial port (sio1) no longer
works.

The output to the onboard serial port works but input doesn't appear
to be accepted. It does appear to be transmitted correctly into the
serial port but remains buffered in the kernel.

If two machines are connected to each other using kermit, and a
backslash is typed on the machine with the broken kernel after
it has received data, the data is released from the buffer and
displayed.

If I recompile /sys/i386/isa/sio.c without PCMCIA support, the
onboard serial port works fine.
