For this application, there is no reason why C would be slow at all.  90%
of your time should be MODEM I/O bound and 9.99% would be disk and the rest
is CPU.  (0.01%)  This is a case where the method is more important than
the language/code.  This should even be doable in "slow" languages such as
(close your eyes, 'cause here it comes) BASIC.  (Assuming you can get at
the correct I/O control functions...)

(No!  I don't do BASIC...  It was just an extreme case...)
