░░░░░░░░░░░░░░░░░░ n the beginning there was Xmodem, and file transfer was
without form and void. Xmodem was the first of the
common file transfer protocols. Xmodem transfers the
file in small packets of 128 bytes each. After each
packet, Xmodem performs a check to insure that the
packet was transferred correctly. You can tell when
Xmodem is performing this check if you have an external
modem because the lights indicating RD or SD (depending
on if you are sending or receiving) stop flashing for
an instant. That instant (actually a substantial part
of a second) represents dead time as far as the transfer
is concerned because no data is being transferred while
Xmodem is performing the packet check.
