Thanks.  I didn't know it, but it also seems to only implement slower
speeds and not [what I find more interesting] V.34 and/or V.90.  Also,
the fact that it's already multi-threading seems a bit odd to me.  In
the end, the modem is nothing but a process that consumes samples and
produces characters in the Rx side, and the inverse for the transmit
side.  Having a kind of library of C functions for this (like linmodem)
seems most natural to me.  But hey, that's a matter of personal
taste.

Regards,
	Harald
