Link Status Messages

Link status messages show you the status of AX.25 connections in which the PK-88 may
be involved.
You can ask for link status at any time from the Command Mode by typing the
command without parameters.
If you attempt a connection when the PK-88 is not in the disconnected state, you see the
link status but the PK-88 takes no other action. The following messages appear in re-
sponse to the CONNECT command.
Link state is: CONNECTED to call1
Your station is connected to a distant station – you'll see the digipeater path in use, if any.
The call sign sequence is the same sequence you would type to initiate the connection.
Link state is: CONNECTED to call1 v2; 2 unACKed
You are connected to a station using Version 2; two frames remain unacknowledged.
Link state is: DISCONNECTED
No link or connection exists right now. You may type the CONNECT command to initiate a
connection.
Link state is: CONNECT in progress:
You have already typed a connect request but have not received the acknowledgment
from the other station. Type the
Link state is: DISCONNECT in progress
You have typed a disconnect request but have not received the acknowledgment from the
other station. Type a second
disconnected state.
Link state is: FRMR in progress
The PK-88 is connected to a distant station but a protocol error has occurred. This should
never happen when AEA AX.25 systems are connected. An improper implementation of
the AX.25 protocol could cause this condition, Your PK-88 will try to resynchronize frame
numbers with the packet controller on the other end although a disconnect may result.
Connections are not valid in this state; a disconnect will start the disconnect process.
