- FWIW, if an internal modem is installed (jumpered to COM2 and IRQ3 on
- the modem board), it may be necessary if not essential to disable any
- onboard (motherboard or serial card) serial port which uses the same
- COM and IRQ. This is typically done on on older systems by setting or
- removing a jumper on the motherboard or serial card, or possibly by
- setting a DIP switch. Newer systems may have the COM ports set through
- the BIOS setup.
-
- So, even though you cannot detect any COM or IRQ conflict with MSD,
- you need to check that any onboard serial port using COM2/IRQ3 is
- disabled in order to avoid a conflict with an internal modem using the
- same settings.
-
- Also, in Win 3.1 Control Panel, under Ports, set the correct I/O
- addresses and IRQs for any COM ports you are using (and make sure to
- use the same settings in your comm software if necessary).
-
- Hope this helps.
