V. Port(s) do not time out
A. 'Robust' X-on/X-off present.
Some printers, particularly the HP LaserJet, send X-on codes at timed
intervals. Set the 'REVERSE CHANNEL DATA TIMEOUT' feature to Y. See
'CONFIGURATION' section for information on 'REVERSE CHANNEL DATA
TIMEOUT'. Other options are disconnect pin 3 on port O, configure the
printer for normal X-on/X-off, or configure port O to X-on/X-off.
B. Improper wiring
A computer which is powered off is making a port busy. Do not connect this
computer's pin 6 to the unit. Alternately, enable ALLOW TIMEOUT ON
BUSY. See 'CONFIGURATION' section for information on 'ALLOW
TIMEOUT ON BUSY'.
