- ~I have been working with someone that is having a problem with
- ~Windows 3.1 trying to start ANY app using COM2 (his internal modem).
- ~The Win error message is the one about "com port is invalid or in
- ~use". No other Win (or DOS) app is running. The reason for the
- ~error is NOT obvious to me. I do not have physical access to the
- ~machine. PD has been by e-mail.
-
- ~Running MSD in DOS shows expected machine config:
- ~Older (circa '92) 386 PC/AT clone, MSDOS 6.2
- ~com1 at 03F8, IRQ 4
- ~com2 at 02F8, IRQ 3
- ~The machine has a pretty basic config, and no i/o address or IRQ
- ~conflicts are apparent. There is a Logitech PS/2 mouse, game
- ~adapter, VGA graphics card, one (1) hard drive, one printer (LPT1
- ~at 0378, irq 7).
- =================
-
- 1. Have them open Ports in Control Panel and check the Advanced settings.
- These settings are reflected in system.ini/[386Enh] where Windows gets its
- configuration info from. The other settings aren't important unless they're
- using Terminal, however the IRQ and Address settings are. Double check for
- COM2Irq=3 and COM2Base=02F8 in system.ini. Address and IRQ in MSD, [386Enh],
- their Comm software and modem setting should all be the same. If all 4
- places match things should work. The 8-N-1 garbage is set via the Comm
- software.
-
- 2. One other *very important* factor. If their serial/parallel I/O board
- has a COM2 port for attaching an external modem it 'Must be Disabled'. Will
- need the book or hopefully there will be marks on the board telling how to
- disable the port. Otherwise they will have to use COM 4.
-
- My guess is #2.
