Pshare and pdelay are intended to enable a port for bidirectional
use, but both are badly broken.  This has been confirmed by IBM
software support.  The best you can do is to enable a port for
dial in (say /dev/tty1), then do something like this if you want
to dial out:

        pdisable 1
        chmod 666 /dev/tty1      # Needs root permissions - ugh!
        kermit                   # or whatever ...
        penable 1

I posted an ugly script to simplify this process last week,
but it's still a big pain.  I encourage you to get after IBM
to fix this.
