MS400.4
Planning:
---------
Unfortunately, you must plan your use of the ports since the exact
placement of the parts is dependent on the change. First determine
how many ports will be for BBS use only and how many should be for
general use.
Some possible variations are below. Note that the numbers must
be consecutive.
Multipurpose ports BBS Ports
------------------ ---------
none COM 3,4,5,6
COM 2 COM 3,4,5
COM 1,2 COM 3,4
These are not all the possible permutations. In fact, two cards could
be used to provide 8 BBS ports if you like. Trying to explain how to
set up all the possibilities would take many many pages of text.
The change outlined below forces all the BBS ports down IRQ2 leaving
the standard COM1 and COM2 IRQ lines alone.
