COMMAND LIST & COMMAND SYNTAX
The Terminal Node Controller (TNC) uses many variable parameters, such as your call sign, termi-
nal type, display preferences and the characteristics of your radio in its operation.
In addition, you can command the TNC to perform several tasks, such as connecting to another
station to start a conversation, disconnecting at the end of the QSO, or displaying information
about itself.
You can change parameters and issue instructions to the TNC by typing commands comprised of
word abbreviation called key-words, or by typing variables that consist of numbers or strings of
characters you select.
You will probably never change some of these parameters. The TNC is designed to provide you
with maximum flexibility so you can adapt it to your particular environment.
The enclosed diskette contains all the commands which are listed alphabetically. You can print-out
those commands by typing from the A: prompt on the computer, like
A: TYPE MANUAL.DOC > PRN
You may also edit this ASCII file trough your favorite word-processor or screen editor.
If a command has parameters, each parameter is described and the default value is given. The de-
faults are the EPROMs stored values, which you may load by typing the
parameter is described and the possible values are given.
Refer to the "OPERATION" section for more detailed discussion of many of the commands and
their interrelationships. Enter the command in the TNC by typing it when you see the command-
mode prompt:
cmd:
The command key-words and parameter are separated by spaces and the TNC takes action after
you press the RETURN [
You may enter key-words in upper- or lower-case.
You may abbreviate all commands and alphabetic parameters to the shortest unique sign. These
minimum abbreviations are shown to the left of each command's full name.
There are several types of parameters. A parameter denoted as 'n' is a number and can be given
either in decimal or in hexadecimal (base 16). When the TNC shows some of these parameters
(those which set special characters), they are given in hexadecimal.
A hexadecimal number is distinguished from a decimal number by the "$" prefix that precedes it.
The "digits" of a hexadecimal number represents powers of 16, analogous to the powers of 10 rep-
resented by a decimal number.
