The ARNET intelligent cards interleave data headed to printer and screen, and 
properly handle incoming keystrokes.
Without the ARNET intelligence, it is still possible to print to the serial
port on any VT100 compatible terminal, but the terminal is useless for the 
duration of the print job.  If you don't also "lock" the keyboard, you could
have keystrokes echoed to your printout as well.
I don't lock the keyboard, since some terminals recognize the code and others
don't.  The print control is recognized by most terminals, as well as Kermit
and Procomm.

# mc5i - echo "\033[5i\c" - print without displaying to screen
# mc4  - echo "\033[4\c"  - turn off local print
