Another reason might be a unreliable RF link causing a high packet loss. Since during the
discovery phase there isn't any retransmission mechanism, it is quite possible that you
managed to "see" the radio, but you weren't able to connect to it, because the connection
request packet was lost. In such case, try to connect again.
4. High drop rate - screen freezes momentarily - connection times out
There are two possible causes.
1.
The link between the client (PC) and the server (radio) is very weak. If the packet drop rate is
more than 20%, then the connection is problematic.
2. There are multiple sessions opened on the same server. With many concurrent sessions the
server response may be noticeably slower. Always close the session gracefully by executing
the
logout radio command, and not by closing the MS-DOS console. If the logout command
is not issued the session at the server will remain open for an additional 15 minutes. Use the
list long command to find out the number of open sessions.
5. If I leave the client inactive for half an hour, and try to type a new command, I get an unable to
transfer packet message or I get a "session timeout - application will be closed" message.
An open session times out after 15 minutes of inactivity on the server side, and 30 minutes on
the client side.
