SUMMARY: Serial ports under Solaris 2.4

Got 5 replies - and from these I've managed to get AdminTool
back working as before (by commenting out ttya and ttyb in
/etc/saf/zsmon/_pmtab and rebooting), but I'm still unable
to get the ports working like they should.

Specifically, we have a Polhemus 3space Isotrak digitizer
that we connect to the serial port. It used to work just
fine. Then one day, it was suddenly inaccessible thru the
serial port. I've tried connecting it to another machine
and it works fine there. Perhaps our only recourse is to
reinstall the OS?

Thanks for the advice,

Matt Marlow
