Set channel list default channel, n is
channel number
Search free channel
Modem searches for next traffic-free
channel. Listening time of traffic is
about 2 seconds
Modem shows next free channel by
activating command again
Get active channel number
Set modem to channel number n in
channel list
Get channel info.
Index nn=[0...(number of channels-1)]
Set channel info.
Format is
SL$L=Iaa,Nbbbbbb,Fcccccccccc,Wddd
ddd,Peeeee<CR> or alternatively
SL$L=Iaa,Nbbbbbb,FTccc.cccccc,FRcc
c.cccccc,Wdd.ddd,Peeeee<CR>
where capital letter marks parameter
field and the following decimal
number presents its value.
aa = Index (0...39)
bbbbbb = Channel number (-
32767...32767)
cccccccccc = Tx/Rx Frequency in MHz
(only numbers or "." allowed, "," is not
allowed)
F field defines a common frequency
value for Tx and Rx
FT field defines Tx frequency
FR field defines Rx frequency
dddddd = Channel spacing/width in
kHz (12.5, 20 or 25), trailing decimals
are tolerated e.g. "25", "25.0", "25.00"
and "25.000" are all valid)
eeeee = Transmitter power in mW
(0...35000) (modem rounds the value
to the closest applicable)
Note: 0 means "don't care" value for
power.
<CR> = Carriage return character
Get status of channel list. 0 = Not in
use, 1 = Channel list in use
