2. The TNC is in transparent mode, and typing just results in transmitting. See
the “Getting out of Transparent Mode” section in the “Modes Of Operation”
chapter.
3. The TNC is in a different interface mode, and needs a different communica
-
tion program, or the interface mode needs to be “exited” back to terminal
mode. See the “Getting out of Host Mode” section, below.
4. The TNC has parameters set in such a way that return to command mode is
not possible. In this case, a Hard Reset will be necessary.
Getting Out of Host Mode
If you want to use a “standard” terminal program after you have used a Host
mode program, be aware that your TNC may still be in host mode when you first
turn it on. If it is, you will not see the normal sign on message, but instead will
see the message “
SØØ ”,sent by the TNC to indicate that it is in HOST
Mode. If you see this message, you must first exit the Host Mode before you can
start talking to your unit with a program such as Pacterm 2.0. You must send
three characters to the TNC in order to exit the Host Mode. First, send a FEND
character (ASCII code 192), then the letter q (upper or lower case is ok), and fi-
nally another FEND character. Your TNC will then leave Host Mode and send
the usual Kantronics sign-on message. )
To send the 3-character sequence from your keyboard, do the following:
1. Press and HOLD the ALT key. Type the numbers 192 from the numeric
KEYPAD (do not use the numbers above the letters on the keyboard). Then
release the ALT key.
2. Type “Q”.
3. Press and HOLD the ALT key. Type the numbers 192 from the numeric
KEYPAD (do not use the numbers above the letters on the keyboard). Then
release the ALT key.
