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, Secondary Station
Identifier), 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. KBØNYK-3. If the
extension is not entered, it is set to -0, and extensions of -0 are not displayed by the
MT1200.
text
There are some commands, which have a parameter text string. This string can be any
combination of letters, numbers, punctuation, 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 carriage return,
into the string by preceding them with the PASS character. The string ends when you
type a (non-passed) carriage return.
Entering Commands
To enter a command, the MT1200 needs to be in COMMAND Communication Mode (as
opposed to CONVERS or TRANS communication mode).
The prompt for Command Mode is:
cmd:
➔
Hint:
Once you go into Packet Convers Mode a <Ctrl+C> (see COMMAND) needs to be
entered to return you to the Command Mode. In the Packet Transparent Mode or
MODEM Mode, a special sequence is needed to return to Command Mode (see
CMDTIME).
➔
Hint:
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 type a <Ctrl+C>, to see if you are already
in Command Mode. If the prompt does not appear then you are either in Command
Mode or in Transparent Mode. If you are in Command Mode, typing a Return will
generate the “cmd:” prompt. If you are in Transparent Mode, you will not get the “cmd:”
prompt when you press the Return key; instead, you need to enter three <Ctrl+C>s in
rapid succession to switch to the Command Mode and get the “cmd:” prompt.
