Flowchart 5: Maintenance Terminal Problems

Ensure that the terminal parameters are set
correctly. They are:
VT100 / 8 Bits / No Parity / One Stop Bit
ASCII character set
Xon/Xoff flow control
300-38, 400 baud
Pin 4 & Pin 7 high
Try a screen reset by toggling the power off
Try a selection of baud rates from 300-38,400 and
press Esc-6 after each change.
Hint: If communication was lost during a session, the
system considers the terminal logged-in and will only
respond at the current logged-in speed. Try setting to
the same speed and press Esc-6 (quit) (or Esc-5 from
Maintenance application).
If communication was never established, the system
should respond at any speed.
Verify terminal and cabling to the maintenance
port.
If available, try connecting to a Peripheral Bay.
Check the switch settings on the CRC.
If a modem is connected, disconnect it.
Try Resetting the system - Hint: Remember to
advise users of loss of service.
Refer to the Maintenance Terminal Troubleshooting
Procedures in the SX-200 EL/ML Technical
