Chapter 5 Packet Operation
In packet,
ID
is an immediate command that sends a special identification packet. The
ID
command allows you to
send a final identification packet when you take your station off-the-air. ( HID must also be set ON ). The
identification consists of a UI-frame, with its data field containing your
MYALIAS
(if it’s entered),
MYCALL
, and
the word “digipeater”. The
ID
packet is sent only if your DSP has digipeated any transmissions since the last
automatic identification.
ILfpack ON | OFF Default: ON
Mode: packet Host: IL
ON
The DSP ignores all
LF
characters sent by your computer.
OFF
The DSP transmits all
LF
characters sent by your computer.
The
ILFPACK
command permits you to control the way the DSP sends
LF
characters received from your computer
while in the packet mode.
Maildrop Commands are completely listed in the Maildrop chapter, Chapter 7
MAXframe
n Default: 4
Mode: packet Host: MX
“ n ” 1 to 7 signifies a number of packet frames.
MAXFRAME limits the number of nack ed packets your DSP permits on the radio link and the number of sequential
packets your DSP will send.
The optimum value of
MAXFRAME
depends on your local channel conditions. In most cases, the default value of
MAXFRAME 4
works well. When the amount of traffic is heavy, the path in use is poor, or if you’re using many
digipeaters, you can actually improve your throughput by reducing MAXFRAME .
Use
MAXFRAME 1 for best results on HF packet.
MBEll ON | OFF Default: OFF
Mode: packet Host: ME
OFF The DSP won’t send any BELL characters to your computer while monitoring packets.
ON
Will send 3 BELL characters to the terminal when the callsign(s) of the station(s) monitored match the
MFROM and MTO lists.
MBELL can be used to alert you to the presence of a particular packet station (or stations) on the frequency. For
example, if you want to be alerted when KG6ZL comes on frequency, you’d enter:
cmd:
MBELL ON
cmd:
MONITOR 4 (or the value you prefer)
cmd:
MFROM YES KG6ZL
cmd:
MTO NONE
With
MBELL ON
, packets from—and to all—stations are displayed, but only those packets matching the
MFROM
and MTO lists cause BELL to ring.
MBx call1 [ , call2 ][- n ][ ALL ] Default: NONE
Mode: packet Host: MB
call
The callsign(s) of one or two stations to be monitored.
“ n ”
0 to 15, indicating an optional SSID.
