None Maybe a simple interrupt problem, maybe worse...

"transmit timeout" may just be an interrupt conflict.  That might
actually be easier to diagnose using the modem.  You can do:

setserial /dev/modem irq 0

to use the modem in polled mode.  If that works, you know you've got
an interrupt conflict.  So... I'd then start excluding interrupts in
/etc/pcmcia/config.opts, and see if you can get the modem to work
without the setserial command.

Be warned that Toshiba laptops have known problems with Linux PCMCIA,
and the RBEM cards are also troublesome.  So this is a particularly
vexing combination.  Also, there is a bad interaction in Red Hat 6.1
that may affect operation of the modem.  All these things are talked
about in the latest BUGS file, at:
