[Dxspider-support] Hamclock connections

[Dirk Koopman]

As you seem to have his ear, could I suggest three things:

1. Reset the timer if he receives *any* data.
2. Increase the timer to something reasonable like 5 minutes.
3. Use the command 'ping' with no arguments (not too frequently). It 
will return a string "Not Allowed' on older versions and 'PONG nn' 
(where nn is an incrementing counter on later versions). Later versions 
will also allow 'ping <string>' which will return 'PONG <STRING>' if 
software wants to maintain their own counter or whatever. The PONG (and 
any string) is always sent back in upper case.

Please, gently, point out to the author that failure to do something 
reasonable may result in measures to prevent his stuff from filling the 
logs with useless data. Please pass my email address to him and 
encourage him to contact me for any help he may need.
