AUTOSTRT {ON | OFF}
default OFF
When ON and operating in RTTY or ASCII mode, the KAM’98 will receive in
-
formation only after it has received the MYAUTOST identifier. It will then con
-
tinue to receive until it receives four “N”s signifying the end of message, or 30
seconds of no signal.
When ON and in AMTOR mode or FEC mode, only AMTOR SELFEC mes
-
sages which contain any of the selcals in MYSELCAL or MYGROUP will be re
-
ceived. Loss of lock will cause the KAM’98 to stop receiving data.

AX2512V2 {ON | OFF}
default ON
This command provides compatibility with all known packet units implementing
AX.25 protocol. When ON, Level 2 Version 2 protocol is implemented and the
TNC will automatically adapt to whichever version the connecting station is us-
ing. When OFF, Level 2 Version 1 is implemented. Set this command to OFF if
you need to digipeat through other units which do not digipeat version 2 packets.
You may also find benefit from setting this command OFF when using several
digipeaters (not nodes) to send packets, or when conditions are marginal between
the two stations involved. (NOTE: Changing this setting after connecting to an
-
other station will have no effect on the current connection.)
The major difference in V1 and V2 protocol is the method used to handle retries.
In the connected mode, if a packet is sent and not acknowledged, Version 1 will
re-send the entire packet and then disconnect if the RETRY count is reached.
Version 2 will first send a poll, the response to this poll will determine if the
packet was received. It is possible that the ack was collided with and therefore
the data packet does not need to be resent. If the ACK shows that the data packet
was not received, it will be re-transmitted. Each time a poll is answered the
TRIES count is reset to 0. If the RETRY count is reached, version 2 will attempt
