Basic
Packet Radio Instructions
|
Here are some basic packet commands that will be used. Assume that
you know how to connect a TNC to the radio, and tuned the radio
to an agreed upon packet simplex keyboard-to-keyboard frequency
(such as 145.03). You've also connected the TNC to the serial port
on your computer and fired up a comm program. Turn on the TNC, and
now what?
I will show what you type in bold . Every line
you type must end with a carriage return, sometimes labeled enter.
First, place the TNC in command mode by holding control down like
a shift key and typing the letter c. Doing this is called hitting
CTRL-C . The TNC will show:
cmd: First, define your call sign:
cmd:MYCALL KF6ABC Let's say you want to connect to KF6DEF:
cmd:C KF6DEF When the connection is established
you get:
*** CONNECTED to KF6DEF and your TNC will switch into converse mode. Now, everything
you type will be sent to the other station and they can type back
to you. As you type a line, you can make corrections with the delete
key, but once you hit return, the line is sent to the other computer
and you enter the next line of text.
For the Regatta, the scoring computer will need the data in some
format. For example, the start and finish times for boat 17 may
look like:
S 17 10:23:54
F 17 10:54:13 To disconnect,
enter CTRL-C , then:
cmd:D
If you can't make a direct connect, you can go via
another TNC acting as a digipeater. To find out who else is on frequency:
cmd:MON ON
cmd:MFROM ALL Try out any call
you see flash by:
cmd:C KF6DEF V W6PW-3 All stations may have to switch frequency
to access a digipeater node such as NAVY on 144.99 and use:
cmd:C KF6DEF V NAVY That's it, have fun. |
