Shane:

	I've been using Multitech's USB modems on RHEL3 just fine.  There
were some driver setup issues to deal with and a mknod operation to create a
special device for them.  Have you done anything equivalent to the Robotics
mode?  Do you have any documentation for their use on Linux?

Hmm, doesn't seem to work...

echo "atz" > /dev/usb/ttyUSB0
-bash: /dev/usb/ttyUSB0: No such device

echo "atz" > /dev/usb/ttyUSB1
-bash: /dev/usb/ttyUSB1: No such device

(I tried all the way up to USB9)

RedHat official support says USB modems are not supported.  But I have
a feeling there should be a way?

Thanks,
Shane
