- 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.
