[Gumstix-users] Modem / 8250.ko

[Chris <c.e...@bt...>]

Sorry to resubmit this problem, the mailing list was down earlier and i =
was lost in the backlog of messages.=20

I have audiovox rtm-8000 modem in cfstix slot, it shows 'tx' but no =
'rx'. I have performed the kernel hack at =
http://www.pegasushabproject.org.uk/cfgps.html which freed up my tty's =
but a new problem seems to be related to irq?

# cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16C950/954 port:C4860400 irq:49 tx:169 rx:0 CTS
1: uart:unknown port:00000000 irq:0
2: uart:unknown port:00000000 irq:0
3: uart:unknown port:00000000 irq:0

# cat /proc/tty/drivers

/dev/ptmx            /dev/ptmx       5       2 system
serial               /dev/ttyS       4 64-67 serial
PXA serial           /dev/ttySA      4 68-71 serial
pty_slave            /dev/pts      136 0-1048575 pty:slave
pty_master           /dev/ptm      128 0-1048575 pty:master

No 49 irq is used by the serial :-(
seems like 8250.ko should be patched :-(

Is there a way around this? Getting a modem working on a gummy should =
not be such hard work, why have something so small that is not portable? =
What is the point of putting a gummy in your pocket if it cant do =
anything in your pocket?

Thanks
