Page 128
CHECKV
1 ON|OFF
Mode: Packet
Default: OFF
The CHECKV1 parameter enables the automatic idle-link- disconnect feature for
AX.25 Level 2 Version 1 connections. The idle time before disconnecting will be
equivalent to the AX.25 CHECK parameter (see CHECK command).
CONP
ERM ON|OFF
Mode:
Packet
Default:
OFF
Parameters:
ON
The current connection on the current stream will not be
allowed to enter the disconnected state.
OFF
The current stream may be connected to and disconnected
from
other
stations.
This command, when switched
ON
, forces the MFJ TNC to always maintain the
current connection, even when frames to the other station exceed
RETRY
attempts to get an acknowledgment.
RESTART
and power off/on cycling will not
affect this connected state.
This command only takes effect when a connection is established. It functions on
a stream-by-stream basis when multiple connections are allowed.
It is useful for certain networking applications, meteor scatter and other noisy,
less-reliable links, while still allowing connections on other streams to operate
normally (automatic disconnect based on
RETRY
, etc.).
CM
DTIME
n
Mode:
Packet
Default:
1
Parameters:
n
0 - 250, Specifying Transparent Mode timeout value in 1
second intervals. If n is zero, the only exit from
Transparent Mode is to send a BREAK signal or
interrupt power to the MFJ TNC.
This command sets the Transparent Mode timeout value. In order to allow escape
to Command Mode from Transparent Mode while permitting any character to be
sent as data, a guard time of n seconds is set up.
