SQuelch ON|OFF/ON|OFF Default: OFF/OFF
Mode: Packet Host: SQ
_________________________________ Parameters: __________________________________
ON - Your PK-900 responds to positive-going squelch voltage.
OFF - Your PK-900 responds to negative-going squelch voltage.
________________________________________________________________________________
Normally, your PK-900 uses its CSMA (Carrier Sense Multiple Access) circuit to
decide whether or not it is clear to transmit on a packet channel. If there are
non-packet signals on the channel you're using (such as voice), you will want to
use true RF-carrier CSMA by monitoring the squelch line voltage from your radio.
If SQUELCH is OFF (default) for a particular Radio port, the PK-900 inhibits
transmissions when there is a POSITIVE voltage on the Radio connectors squelch
input line. When there is no voltage or NO CONNECTION to this pin, the PK-900
allows packets to be sent.
When SQUELCH is ON, the PK-900 will inhibit packet transmissions when there is
0 volts applied to the squelch input pin on the appropriate Radio connector.

SRXall ON|OFF Default: OFF
Mode: AMTOR Host: SR
_________________________________ Parameters: __________________________________
ON - Receive ALL selective (SELFEC) transmissions.
OFF - Receive only SELCALL-addressed SELFEC transmissions.
________________________________________________________________________________
SRXALL permits the reception of selectively coded inverse FEC signals normally
not available for decoding. Set SRXALL ON to activate this feature on Radio
Port 1.

STArt "n" Default: $11 <CTRL-Q>
Mode: All Host: ST
_________________________________ Parameters: __________________________________
"n" - 0 to $7F (0 to 127 decimal) specifies an ASCII character code.
________________________________________________________________________________
Use the START command to choose the user START character (default <CTRL-Q>) you
want to use to restart output FROM the PK-900 TO the terminal after it has
been halted by typing the user STOP character. See the XFLOW command.
