Don't remember the licence of the binary part. The binary part is the modem itself and the AT-command parsing. The remaning is transporting data. It should be possible to port the driver, but it still contains binary parts and of course there are performance implications for a softmodem. Doing the modulation/demodulation completely from scratch is hard work. I personnaly already thought about building one using an embedded modem together with an FTDI USB-uart. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
