INTRODUCTION TO COMMANDS

flags
ChoiceA | ChoiceB
Many parameters are "flags", meaning they have two possible values, ON and OFF, or YES and NO.
All of the command descriptions show ON and OFF as the options; however YES (y) and NO (n)
may be typed instead. A few parameters are really flags, but rather than indicating that something
is "on" or "off", they select one of two ways of doing things. Some of these parameters have the
values EVERY or AFTER indicating operating modes for data transmission. The possible choices are
separated by a vertical bar. Some of the flag parameters will allow many choices, such as
ON | OFF | TO | FROM
callsigns
xxxxxx-n
Several commands require callsigns as parameters. While these parameters are normally Amateur
callsigns, they may actually be any collection of numbers and/or letters up to six characters; they
are used to identify stations sending and receiving packets. A callsign may additionally include an
"extension" (SSID, substation id), which is a decimal number from 0 to 15 used to distinguish two
or more stations on the air with the same Amateur call (such as a base station and a repeater).
The callsign and extension are entered and displayed as call-ext, e. g. K0PFX-3. If the extension is
not entered, it is set to -0, and extensions of -0 are not displayed by the TNC.
text
There are some commands which have a parameter text string. This string can be any combina-
tion of letters, numbers, punctuations or spaces up to 128 characters. In order to be used all
string parameters must contain at least one non-space character. You can even put characters with
special meanings, such as a carriage return, into the string by preceding them with the PASS char-
acter. The string ends when you type a (non-passed) carriage return.
dual port
KAM
and
KPC-4
only. Some parameters can be set differently for the two radio ports. In the com-
mand descriptions, these parameters are indicated by two default settings separated by a slash,
for example MAXFRAME 1/4. The first parameter is used for the HF radio port (or Port 1 on the
KPC-4
) and the second parameter is used for the VHF port (or Port 2 on the
KPC-4
). There are sev-
eral ways these double parameters can be set.
MAX 2/3
sets HF (Port 1) Maxframe to 2 and VHF (Port 2) Maxframe to 3
MAX 4/
sets HF (Port 1) Maxframe to 4 and leaves VHF VHF (Port 2) Maxframe unchanged
MAX /7
sets VHF (Port 2) Maxframe to 7 and leaves HF (Port 1) Maxframe unchanged
MAX 6
sets both HF (Port 1) and VHF (Port 2) Maxframe to 6
All commands having independent values for the HF (Port 1) and VHF port (Port 2) are set in the
same manner except for HBAUD on the
KAM
(see HBAUD).
