Terminal
Commands
(Only if a local console or modem is attached)
If a terminal or modem is attached to the console port and does not
seem to be operating properly, follow the troubleshooting procedures
recommended by the terminal/modem manufacturer. Also perform the
following steps:
1 Make sure that the cable connections at both ends are secure.
2 Ensure that the cable attached to the AccessBuilder is the proper cable
(straight-through for a terminal/PC and null modem for a modem).
If connecting to a terminal, a straight-through cable conforming to the
VT-100 specification must be used. This applies only to the
AccessBuilder 4000.
3 Check the console port configuration.
Refer to the "AccessBuilder Software Configuration Guide" for more
information. Verify that the terminal/PC or modem is configured as 8
data bits, no parity, one stop bit, 9600 baud rate, with flow control
parameters set to Xon and Xoff (software flow control).
(Only if a local console is attached)
If the AccessBuilder power is on but the terminal fails to respond to
commands entered at the keyboard, try the following procedures:
1 Verify that a straight-through cable is used between the AccessBuilder
and the terminal or workstation running the terminal emulator.
2 Power off the terminal, wait 30 seconds, and then power it on again.
3 If the system still does not respond to commands, power off the
AccessBuilder and terminal and check the keyboard cable connection to
ensure it is secure.
4 Power on the AccessBuilder and the terminal again.
5 Check the state of the LEDs on the front of the AccessBuilder as shown
in Table 4-1.
