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
to re-connect unless RELINK is OFF. If the re-connect attempt is unsuccessful,
then version 2 will issue a disconnect.

AXDELAY n (n = 0 - 255)
Multi-Port
default 0/0
The value of “n” is the number of 10 millisecond intervals to wait, in addition to
TXDELAY, after keying the transmitter before data is sent. This delay can be
helpful when operating packet through a standard “voice” repeater, or when us-
ing an external linear amplifier which requires extra key-up time. Repeaters using
slow mechanical relays, split-sites, or both require some amount of time to get
RF on the air.
