4. Parallel ports, serial ports and mice

4.1 Where are the (microsoft compatible) mouse drivers?

Tom Kimball (tk@pssparc2.oc.com) reported (11/24/93) that

Several people said to use a different mouse driver and suggested some. I found a couple that seem to work fine.

   oak.oakland.edu:/pub/msdos/mouse/gmous102.zip   (gmouse)

4.2 Why doesn't the mouse driver work?

Mark Rejhon (mdrejhon@magi.com) reported (4/7/95) that

If you start the mouse driver and it just hangs (it might actually take 30-60s), but if you are waiting longer than a minute for the mouse driver to start, try specifying the COM port that the mouse is on, at the mouse driver command line.

4.3 Why does dosemu clobber COM4?

Rob Janssen (rob@pe1chl.ampr.org) reported (3/24/94) that

According to jmorriso@bogomips.ee.ubc.ca, "dosemu still clobbers COM4 (0x2e8, IRQ 5). 0x2e8 isn't in ports{} in config. I have to run setserial /dev/cua3 irq 5 on it after dosemu exits."

This is caused by your VGA BIOS. I have found that by enabling the IO port trace and seeing where it was clobbered.

Disable the "allowvideoportaccess on" line in config and it will work fine. When you then have problems with the video, try to enable more selective ranges of IO addresses (e.g., 40-43).

4.4 How do I use dosemu over the serial ports?

4.5 How can I switch between dosemu and a shell over the serial line?

John Taylor (taylor@pollux.cs.uga.edu) reported (5/25/94) that

I am running Linux 1.1.13 and want to point out a great feature that should be protected and not taken out (IMHO). With the 52 version, I can run the program, "screen." From screen, i can invoke dos -D-a. What is really great (IMHO) is the screen commands (the CTRL-A cmds) still work. This means I can do a CTRL-A C and add another unix shell, and switch between the two (DOS / UNIX). This allows me to use dosemu over the serial line really well, because switching is made easy.

4.6 How can I get the parallel ports to work?

Dennis Flaherty (dennisf@flaherty.elk.miles.com) reported (3/2/95) that

The dosemu.conf has lines at the end to redirect printers to either lpr or a file. If you want direct access to the bare metal, comment out these emulation lines, and add the line

ports { 0x3b8 0x3b9 0x3ba 0x3bb 0x3bc 0x3bd 0x3be 0x3bf } # lpt0

ports { 0x378 0x379 0x37a 0x37b 0x37c 0x37d 0x37e 0x37f } # lpt1
ports { 0x278 0x279 0x27a 0x27b 0x27c 0x27d 0x27e 0x27f } # lpt2
