Some soundcards do have full duplex capabilities....
So that is not the bottleneck...
However I guess you will need external circuitry (in the old days they
used to use "acoustic coupler" to fit on normal phone handsets to send
data ...you will probably get connect speeds of 300 bps ... nothing to
write home about.
p.s the low connect speeds are the cause of the short commands in unix
...
ls ,vi etc etc
