Yes - gsm0710muxd creates a new serial device for each application
needing access to the GSM device.  You just call pppd with its own
device.

I've run GPRS for several hours at a time in a car travelling in some
dodgy reception areas.  Sometimes it seemsed to lose connection and
re-establish itself gracefully but more often than not I'd find that
GPRS had died and pppd was still up but ineffective.  I usually had to
reboot the FR before I could re-establish connection when this
happened.
