Binary mode
This mode allows sending a number of bytes defined with parameter

Interactive text mode
This mode allows the user to type and send 8-bit ASCII characters while the
service is open. Ctrl-Z terminates data input and causes the data to be trans-
ferred.
Interactive text mode requires that the
