Is LINUX talking on the right IRQ? If not, this causes things to work
but verrrry slowwwwwly - including causing lights to blink but not
getting anywhere. If your modem is set to an IRQ different to what LINUX
thinks /dev/modem should be, you can change it with the setserial
command or put the fix permanently in /etc/rc.d/rc.serial - something
like:
setserial /dev/modem irq 3
should do the trick (assuming the 'correct' irq is 3).
trying to talk to the modem with minicom should give you a clue if this
is the problem - if things take a long time, bet on the irq being the
problem. If it doesn't work at all, then it may be something else.
If you don't know the irq, you CAN:
setserial /dev/modem irq 0
(where 0 means no irq instead of irq = 0) The kernel will then
communicate with the modem in a different way. This is only an interim
solution though, you should find out what the real irq is and do the
rc.serial stuff when you know.
Good luck,
Gregg
