Practical tests showed transfer-rates below expected 1440 bytes/sec.
Typical values seem to be in the range of 1320 bytes/sec.
What is the reason for the difference ?
What will be the minimum transfer-rate to expect ?
Baud-rate modem/pc was 38400, so there is no problem to fill up
buffers inside the modem and there is no (rts/cts) handshake-related delay.
I didn't use xmodem, but sended a very long file one way - no handshake either.
