INTRODUCTION TO COMMANDS

Introduction to Commands

Some Abbreviations

Ctrl-x = Ctrl is the control key and x represents any alpha character. This is a two key combination.

Press the Ctrl key and while holding it down type the letter x (this can be capital or lower case, but

will be shown as capital). Release both. If your computer keyboard has no key labeled Ctrl, consult

your computer manual to determine which key performs the control key function.

$ preceding a number denotes a hex number (base 16)

<CR> = carriage return, $0D, decimal 13, Ctrl-M

<LF> = line feed, $0A, decimal 10, Ctrl-J

I/O = Input/Output

Computer and terminal are used interchangeably to describe whatever device is attached to talk to

the TNC.

Commands Structure

There are many commands which affect operation of the Kantronics TNCs. Some commands affect

performance under specific conditions, some change parameters affecting general operation and

other direct a one-time action.

The user changes parameter and issues instructions to the TNC by typing commands composed of

English-like word abbreviations and variables which are numbers or strings of characters chosen by

the user. You will probably never change some of these parameters.

Default values are stored in the EPROM and are the settings used at power-on. If you change any

setting or value and PERM it, the new setting or value will be stored in the EEPROM and will be the

value used at future power-on. Parameters which you change but do not PERM will revert to fac-

tory defaults at the next power-on. A hard reset can be done to the factory defaults, as described

in the Installation Manual. If using the optional Battery Backup or SmartWatch all changes parame-

ters are backed up immediately.

Entry

A command is entered to the TNC by typing the command name and its argument (setting or val-

ue) in the Command Mode. The prompt for Command Mode is:

cmd:

The command and argument must be separated by a space, and the TNC takes action when a car-

riage return <CR> is typed. All command entries may be abbreviated to the shortest unique string.

In the command list which follows, those required entries are denoted by capital letters.

You can examine the value of any parameter by typing the command name followed by a <CR>. A

special command, DISPLAY, allows you to see the values of all parameters or groups of related pa-

rameters.

Once you go into Packet Converse Mode or WEFAX Mode a Ctrl-C (see COMMAND) needs to be en-

tered to return you to the Command Mode. In the Packet Transparent Mode a special sequence is

needed (see CMDTIME). In the KAM there are other modes from which you need to enter a Ctrl-C

followed by the letter X to return to Command Mode.

INTRODUCTION TO COMMANDS

If packets have been printing on the screen you may have forgotten which mode you are in. If you

wish to see the cmd: prompt do a Ctrl-C, to be sure you are in Command Mode. If the prompt

does not appear, then you are already in Command Mode, just type a RETURN [↵] if you wish to

see the cmd: prompt.

ormat

All commands are listed alphabetically. On the first line of a command will be the command name

followed by any arguments required. Any optional arguments will be shown in square brackets [ ].

If the command accepts several different values, or a range of values, the permissible arguments

will be shown in parenthesis ( ). The permissible arguments may also be shown separated by a

vertical bar |. At the far right of the first line will be the version number which introduced this com-

mand. The second line will show the default value, which TNCs this command applies to, and what

modes of operation are affected by this command. Example:

COMmand arguments (permissible arguments) version

default units modes

If the command applies differently to different units, the unit name will be in

italic

and listed sepa-

rately.

Parameter Types

n(range)

Any number within the range is permissible. The unit of measures (seconds, ms, baud, count, etc.)

for the number will be described in the description. These are decimal numbers.

n($00 – $FF)

Several parameters are numerical codes for characters which perform special functions. The code

is simply the ASCII character code for the desired character. (See the ASCII Chart at end of this

manual.) Most of these characters have control characters as default value. Control characters are

entered by holding down a special control key on the keyboard while typing an x, then release

both keys. These special characters cannot be sent in Packet unless preceded by the pass charac-

ter (see PASS) or unless you are operating in the Transparent Mode.

These numbers are shown in hexadecimal (hex) form (base 16). They can be entered either in

decimal or in hex. A hex number is distinguished from a decimal number by preceding it with a "$"

prefix. The "digits" of a hex number represent powers of 16, analogous to the power of 10 repre-

sented by a decimal number. The numbers 10 through 15 are denoted by the hex digits A through

F. For example:

$1B = (1 × 16) + 11 = 27

$120 = (1 × 16 × 16) + 2 × 16 + 0 = 288

Permissible values are shown as: (n = $00 – $FF). This is true if 8BITCONV is ON as defaulted. If

8BITCONV is changed to OFF, then permissible values are $00 – $7F. See the ASCII Chart at the

end of this book for character codes and hex/decimal conversion.

If a streamswitch (STREAMSW) character or any other special character is defined as "$" then you

will need to enter values in decimal, or precede the $ with the PASS character in order to enter

hex numbers.

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- 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/ . The first parameter is used for the HF radio port (or Port 1 on the

KPC- ) and the second parameter is used for the VHF port (or Port 2 on the KPC- ). 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 / sets HF (Port 1) Maxframe to 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).

COMMANDS

Commands

8bitconv ON | OFF

default ON All Units All Modes

When ON, transmission of 8-bit data is allowed in the Packet Convers Mode and ASCII Mode. If

you wish to obtain 8-bit data transmission but do not want all the features of Transparent Mode,

set this command to ON. This feature may be most useful for transmitting non-ASCII character

sets. If OFF, the 8th data bit is stripped. This setting corresponds to the Word Length or Data Bits

setting of your communications program. Some terminal programs will not operate properly with

8BITCONV ON. If your terminal operates properly in Command Mode (cmd:) and seems to quit

working in Converse Mode then turn this parameter OFF.
