Can you post output of sin -P Dev ar ?
Palo, I think, interesting it would be to have also snapshot of screen
after boot, listing individual interrupts used by PCI devices.
Those interrupts which are used by the card for com3 a com4 must not
be used by other devices, since Dev.ser behaves racklessly to other
devices sharing the same interrupt - of course, it is only my experience.
Sometimes it is not easy to get such state - you have to switch off as
much interrupts in BIOS as possible - for VGA, USB, Monitor, …
Another (and similiar) problem can be what you have focused - that Will runs
Dev.ser twice (one for com3 and one for com4) and there is only one card
(one device). This could also cause problems.
E.g. instead
Dev.ser -N ser3 c400,11 &
Dev.ser -N ser4 c800,11 &
it should be
Dev.ser -N sup c400,11 c800,11 &
(int his way you get /dev/sup1, /dev/sup2, may be also
Dev.ser -N ser3 c400,11 -N ser4 c800,11 & works but I haven’t tested)
But probably this is not Will’s case since it seems that
he has different interrupts for com3 and com4

i have com 4 on it’s own interrupt, but com 3 is sharing an interrupt. i’m
out
of interrupts to assign, but neither com 3 or 4 works the way i want. i
thought
qnx could support irq sharing according to the dev.ser help. i could be
worng.
i’m fairly new to qnx. thanx for helping. i need lots of it.

after some more testing, somehow after a reboot, i would be able to
transmit one
character through a serial port (i’m using a null modem cable for
testing)
and
then it never transmits again. this leads me to believe the board is
working but
somehow it’s not configured to send and receive correctly. anyone with
any
clues
as to how i can fix this. thanx.
It looks like there is a problem with interrupts.
