UP9600 RS-232 Interface Card notes!

This is the modified version of the RS232 interface on FUNET.  The following
options was added:

1. Now works with Daniel Dallmann's SLIP & MiniTerm programs. Also must work
   with Novaterm 9.6 at 9600bps.
2. DSR disable jumper added (for some software).

You can use MC1488/1489, GD 75188/75189 or other chips with similar layouts:
