reported e.g. Checksum errors are reported
together with the address at which the error
was detected, which is usually the end of the
row in which the error occurred. When a file is
received correctly S4 displays the last address
where code was stored.
Before returning to command mode, S4
waits until the data input has been inactive
for at least one second. This is to "run-out"
any extra data to avoiding hanging-up the
sending computer. When sending from a
batch-file, a delay of over one second must
be inserted before the next command, to
prevent S4 seeing it as "garbage".
