Your PK-232 tries to prevent this sort of "lockup" from occurring depending on
the settings of AX25L2V2 and RECONNECT, by using the CHECK timer as follows:
o If a Version 1 link is inactive for (CHECK times 10 seconds), your PK-232
tries to save the link by starting a reconnect sequence. The PK-232 enters
the "connect in progress" state and sends "connect request" frames.
o If a Version 2 link (AX25L2V2 ON) is inactive and packets have not been
heard from the distant end for "n" times 10 seconds, your PK-232 sends a
"check packet" to test if the link still exists to the other station. If
your PK-232 does not get an answer to the "check packet" after RETRY+1
attempts, it will attempt to reconnect to the distant station.
See the RELINK command.

CHSwitch "n" Default: $00
Mode: Packet Host: CH
_________________________________ Parameters: _________________________________
"n" - 0 to $FF (0 to 255 decimal) specifies an ASCII character code.
_______________________________________________________________________________
CHSWITCH selects the character used by both the PK-232 and the user to show that
a new connection channel is being addressed. DO NOT USE $30 to $39 (0 to 9).
If you plan to use multiple packet connections, you MUST select a CHannel
SWITCHing character. This character will be interpreted by the PK-232 to
indicate that you want to select another "logical" packet channel.
The vertical bar "|" ($7C) is not used often in conversations and makes a good
switching character. To make the Channel Switching character the vertical bar,
simply enter the command CHSWITCH $7C.
To change the logical packet channel you are using with the PK-232, then simply
type the vertical bar "|" followed by a number 0 through 9 indicating which
logical channel you wish the PK-232 to use.
See CHDOUBLE and CHCALL for further information on the use of CHSWITCH.

CMdtime "n" Default: 10 (1000 msec.)
Mode: All Host: CQ
_________________________________ Parameters: _________________________________
"n" - 0 to 250 specifies TRANSPARENT Mode time-out value in 100-millisecond
intervals.
If "n" is 0 (zero), exit from Transparent Mode requires sending the
BREAK signal or interruption of power to the PK-232.
_______________________________________________________________________________
CMDTIME sets the time-out value in Transparent Mode. A guard time of "n" times
10 seconds allows escape to Command Mode from Transparent Mode, while permitting
any character to be sent as data.
