I doubt that this is the reason. In 1/70 s only 164 characters get through
a line with 115 kbps, which should easily fit into the HSMODEM buffers.
Basically the same holds for STinG. It were a different matter if it were
the CPU not being able to process these 164 bytes in 1/70 s, but that's
unlikely too because the TT should be able to deal with significant higher
rates then.
