Unsuccessful Connections and Retries

Sometimes your connect request can't be completed; the desired station may not be an
the air, it might be out of range, or you could have mis-typed the other station's call sign.
If your PK-232 does not get a response to its first connect request packet, it will try again.
RETRY
Use the
nect request. The default value is 10. If your PK-232 doesn't get an ACK after that num-
ber of repeats, it quits and show:
*** Retry count exceeded
*** DISCONNECTED: (call sign)
4.6.10.1 Retries While Connect
The same try mechanism and count continues after the connection is established,
you're in Converse Mode and the QSO has started. Each packet frame sent by your PK-
232 must be "acknowledged" or ACKed by the other station and vice versa. ACK means
that the packet was received correctly at the distant station; the error-detection proto-
col indicated it was received without errors. (This is how Packet-Radio provides error-
free communication.)
Sometimes a packet won't be received correctly by the other station, because of chan-
nel noise. If your PK-232 doesn't get an ACK within a specific time, it sends the same
packet again and increments the retry count. If the count set by
your PK-232 disconnects and displays:
*** Retry count exceeded
*** DISCONNECTED: (call sign)
The automatic disconnect feature avoids excessive retransmission of unless packets. If,
for example, the other operator turns off his station without disconnecting, or your path
is trough a digipeater that is shut down, or the RF channel deteriorates to the point of
being unusable, the disconnect prevents a "hopeless" condition from trying up the
channel.
