computer. The same baud rate selected for the relay must also be selected on the external terminal or
computer.
Serial Communication
Front and rear serial port communication cannot take place at the same time. Priority is given to the front
panel port.
If communication is in progress but no keys on the terminal are typed for five minutes, communication is
stopped. A fixed timeout of five minutes in the relay software allows switching devices such as the SEL
PRTU or RFL 9660 switch to regain communication at the rear port in case the front port is left unattended
or connected.
If rear port communication is taking place when the front port is connected, rear port communication must
be stopped before front port communication can begin. Two methods are available to stop rear port
communication. They are:
Keystroke ESC (to enter the main menu) must be typed on the front (local) terminal/computer.
Keystroke Q (to exit the main menu) must be typed on the rear (remote) terminal/computer.
An XON (Ctrl-Q) may be needed at the front port to start communications if the rear port had recently
received an XOFF (Ctrl-S). To allow rear port communication to continue, the front port must exit from the
main menu with the Q keystroke or allow the five minute timeout to stop communication.
Use built-in functions in the modem software to print screen data or capture data to a file. No special
commands are needed to retrieve data other than a few keystrokes to select the desired screen. Each
screen is displayed by transmitting a series of information strings. The information can be raw data, such
as the text that comprise column titles or escape sequences that are interpreted by the VT-100 compatible
terminal to perform various functions such as clearing the screen, positioning the cursor, set screen
attributes, etc. Lines on a screen can be displayed in any order. In fact, screen information is displayed in
a totally random fashion (bottom lines can be transmitted prior to top lines, right most data can be displayed
prior to left most data). XON (Ctrl-Q) and XOFF (Ctrl-S) can freeze data on the remote terminal or computer
screen as the screen is being updated.
Starting Communication
With a computer or terminal connected to the relay and the modem software operating, begin communication
by pressing the ESC key (refer to Figure 1-1 for screen flow diagram and keystroke sequence). Screen 1,
MAIN MENU, appears on the monitor when communication begins. From this point on, the communication
is menu driven. Select the desired main activity (screen number) to continue or Q to exit. Movement is
made within the screens with standard arrow keys
. To refresh the screen with the latest data, use
Ctrl-R. For full details of all other screens refer to publication 9 2315 00 991,
Terminal Displays and
Settings.
Downloading And Uploading Settings
All of the settings stored in a relay (except for passwords) may be retrieved through communication ports.
Once they are received, the settings may then be uploaded to another relay or printed. For downloading
or uploading settings, you must start communication as described in the previous paragraph to get the MAIN
MENU on the screen and then follow the procedure described in
Downloading Settings or Uploading
Settings.

After the MAIN MENU is selected, type Q to exit the screen. This prepares the relay to receive the next
