Integrate serial emulation code to uses external serial emulation software

[fpietrosanti]

minimodem is an excellent tool that may really fill the gap in the missing piece of technology landscape, being able to connect with an FSK modem using VoIP.

IMHO the missing component here is to have a serial interface emulation that would enable to use external piece of software (being a wardialer, an UCP/TAP SMS protocol, whatever).

Consider also looking for integration at BBS Revival Project that's looking at the same cornerstones:
