SIgnal Immediate Command
Mode: All Host: SI
________________________________________________________________________________
SIGNAL is an immediate command that causes the PK-900 to enter the Signal
Identification and Acquisition Mode (SIAM). The PK-900 will respond with:
Opmode was BAudot
Opmode now SIgnal
After a few seconds the PK-900 will show the signals baud rate. A few seconds
later it will identify the signal type.
________________________________________________________________________________
SLottime "n/n" Default: 30/30 (300 msec.)
Mode: Packet Host: SL
_________________________________ Parameters: __________________________________
"n" - 0 to 250 specifies the time the PK-900 waits between generating
random numbers to see if it can transmit.
________________________________________________________________________________
The SLOTTIME parameter works with the PPERSIST and PERSIST parameters to achieve
true p-persistent CSMA (Carrier-Sense Multiple Access) in Packet operation.
The value for each Radio Port defaults to 30 (300 msec.) for VHF operation.
For HF packet operation, a value of 12 is recommended. See the PPERSIST and
the PERSIST commands for more information on this parameter.
________________________________________________________________________________
SPACE "n" Default: Current modem space frequency
Mode: Command Host: Sp
_________________________________Parameters_____________________________________
"n" - 500 to 3000 specifies the transmit space frequency in Hz.
_______________________________________________________________________________
The SPACE command is used to select a non-standard space tone transmit fre-
quency. The space tone frequency range is 500 to 3000 Hz. If the SPACE
command is entered without an argument ("nnnn"), the current space frequency
is displayed.
