If the terminal gets “garbage” data, check the speeds of the host and
remote multiplexers, the terminal and the computer ports to make sure
they match.
Blocks of data are lost most often when data is sent to a printer or a lot
of data is being displayed on a terminal. Most of these problems are due
to flow control not matching between the printer or terminal and the
multiplexer.
If terminals and printers work for a while and then “hang”, check the
flow control settings. When Xon/Xoff flow control is set to a different
parity on the multiplexer than on the terminal or printer, the result is
either a “hung” device that is flow controlled off but never back on, or a
device that is never flowed off causing buffer overflow and lost data.
