logitech bus mouse problems: a solution

[Mike Nemeth]

the following will probably only be of interest to people using a
Logitech Bus mouse and ISC 3.2.2. if you can't get both your modem
and your mouse to work at the same time, read on...



hardware: IPC 25Mhz 386, Future Domain SCSI controller, Logitech Bus mouse,
          USR Courier v.32 modem
software: ISC 3.2.2 upgrade from 3.2.0.2, FAS 2.05 or 2.07
mouse interrupt: 3 (because FD SCSI controller uses 5 and cannot be remapped)
serial port #0 interrupt: 4 (only 1 serial port configured)

under 3.2.0.2, uugetty sucks like a chest wound, so i configure in
FAS 2.07 (displacing "asy"), modem now works, mouse won't work.

ie.

% cat < /dev/logi

produces nothing. dead like dinner.

remove FAS driver, mouse works, but then i'm stuck with uugetty (ugh!)
under 3.2.0.2. so i live without a mouse for awhile. modem works fine.
eventually upgrade to 3.2.2, which has support for a bi-directional port.
toss uugetty, can run straight /etc/getty on new device /dev/tty0d. build
a kernel using ISC asy driver, reboot system, mouse works BUT now something
else is broken! modem answers phone, but getty ignores it. i can picture
extremely irritated user at other end of serial link beating on keys
and cursing the air blue. play with modem, it's fine.

read manual, check inittab, check gettydefs, check configuration,
check board interrupts, and discover nothing supposedly wrong.
okay, so maybe the 3.2.2 asy driver is ill. build another kernel
with FAS 2.07 and no asy driver, reboot, modem now works but mouse
is deceased again.

eventually i found the following solution:

change mouse configuration (/etc/conf/sdevice.d/asy) interrupt to "9",
change Logitech Bus mouse board jumper to "2". build another kernel
leaving asy out and FAS 2.07 in. power off and reboot, modem works
and mouse works too, and nothing else seems to have broken (yet).
