Re: [X] why does X kill my modem?
Hello Bob, sounds like you need to re-do those IRQ's. Here's my setup:
ttyS0 = disabled
ttyS1 = IRQ 4 (mouse)
ttys2 = disabled
ttys3 = IRQ 2 (modem)
I use IRQ 3 with my NE2000 network card, so COM 1 & 3 aren't used 8-)

Only thing I can think up at least. Other than that it works fine! Jason -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .

The old story of telling someone 'you can't do it' when they don't know
they can't do it. :-)
I have this set up running under Linux for almost 2 years now and never
had problem--so long as I don't run X. (Knock on silicon!)

I should be able to. I'll give it a try and see what happens.

You have 2 sets of hardware sitting on the same irqs. This will cause confusion. With standard serial ports, this will never work reliably. Can you set any of the ports to another irq?

I *meant* to type:
ttyS0 and ttyS2 are IRQ 3
ttyS1 and ttyS3 are IRQ 4

ttyS0 and ttyS3 are IRQ 3
ttyS2 and ttyS4 are IRQ 4
I keep the modem (on ttyS4) separate from the mouse (on ttyS0) to avoid
conflicts.
The X10 controller on ttyS3 should not be a problem. It uses a software
UART. It *never* sends anything on its own. It only sends something in
response to a query from my machine. That only happens once a week in the
early morning hours to sync the controller's clock. It also happens
occasionally to update the controller to adjust for seasonal changes.
All this works fine when X is not running. This is why I'm puzzled to
what X is changing.
Any other ideas?
Bob

If you are sharing 3 and 4 between 3 devices, that could be the problem. Tim -- (work) [EMAIL PROTECTED] / (home) [EMAIL PROTECTED] - http://www.buoy.com/~tps Madness takes its toll...
