You can be sure that the $70 modem is using half-duplex (probably
202-type) formats, not full-duplex 212A formats.  Also, the 2400 bps
communications are also almost certainly using a wide-deviation half
duplex format that bears no relationship to V22.  Don't depend on
being able to successfully record (on tape) such transmissions--the
wow/flutter on many audio tape recorders (particularly cassette
machines) can sometimes make even 202 recording difficult, and would
be even more of a problem at 2400 bps.
