SENDPAC
Use default
intervals with <CR> included in the packet.
CPACTIME
When setting
with CR OFF. This setting forces packets to be sent without extra <CR> characters being sent in
the text.
SQUELCH ON|OFF
Mode: Packet
Parameters:
ON -
OFF - Your PK-232 responds to negative-going squelch voltage.
Normally, to decide if the channel is clear so that it can transmit, your PK-232 uses its CSMA (Car-
rier Sense Multiple Access) circuit by sensing audio mark and space tones from your Packet re-
ceiver.
If there are non-packet signals on the channel you're using(such as voice operation), it's possible
that your PK-232 might not be quite as polite as it is normally and double with the other signals.
The PK-232 can use true RF-carrier CSMA by monitoring the squelch line voltage from your radio.
This line can be easily connected in many radios to the "busy" light or indicator on the radio's front
panel, or to other circuit locations that indicate the presence or absence of carrier or received sig-
nals. Because your carrier-sensing signal can be active-low or active-high (depending on the indi-
vidual radio manufacturer's design), you can set your PK-232 to sense either positive or negative
squelch voltages.
SRXALL ON|OFF
Mode: AMTOR
Parameters:
ON -
OFF - Receive only SELCALL-addressed SELFEC transmissions.
SRXALL
permits the reception of selectively-coded inverse FEC signals normally not available for
decoding.

Use the
command to choose the user START character you want to use to restart output
from the PK-232 to the terminal after it has been halted by typing the user STOP character.

You can enter the value in either hex or decimal.
If the User Start and User Stop characters are set to $00, software flow control to the PK-232 is
disabled; the PK-232 will only respond to hardware flow control (CTS).
