My view:
Since PPP expects a serial transparent interface, and you are not
providing that, I would write a "tap" which provides that to PPP and
"taps" all other data out.

GSM modem ----> real serial --> my module -----> PPP virtual serial

                                    -----------> tracking virtual serial

Some GSM modems provide a packetization interface to clearly separate
muxed channels on the same serial interface. If yours does not, you'll
have to work harder.
