Hi All,

this message was skipped in .students newsgroup , so I took a risk of 
posting it here...

I am starting to transfer my application (CBuilder 6.0) towards the 
support of the network. Since I am very new in this business I will 
appreciate any advise.

Application controls some hardware in a time critical manner. Let call
it server. Server does: execute commands, acquire data (asynchronously),
+transfer data on request (let say 0.5Mb every hour),
+inform about current state and report errors (not too frequently).

The idea is to write client which will look exactly like current
application but manage hardware remotely.

Questions:
which components to use (Indy ?)
which protocol and port better to use ?
what is better: to keep connection alive or poll server periodically?
Related question what to do with errors, sending of which have to be
initiated by server.
some hints for developing of the protocol - string-base or binary form ?

Regards,
Boris
