changeing irqs on serial devices.
Hey there,
On my home computer i currently have a modem and a mouse, both serial. I
like haveing multiple displays how ever and since i resently came
accross a dumb terminal i thought that i would connect it.
So far however i have not been able to get the dumb terminal to work at
the same time as the modem. This is (i think) because they are sharing
an irq.
The modem is currently on ttyS3 and the Dumb terminal is on ttyS1.
Since the modem has hardware switches on it to change the irq i tried
changeing them so that the modem was using irq 5 and then 7. with both
of these changes the modem would dial (slowly) and then hang up after
giving...

I guess that this might be useful...
krondor:~# setserial -g /dev/ttyS0 /dev/ttyS1 /dev/ttyS2 /dev/ttyS3
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1: Device or resource busy
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: 16550A, Port: 0x02e8, IRQ: 3

Is there any easy way that i can make all of my serial devices play
nicly together?
any help would be much appreciated.
Thanks.
Tim
PS. i also played with setserial trying to change the irqs for the
troublesome devices. It didn't seem to have much affect.
