Several exchange libraries are provided by default (beam, local, 
Bluetooth, versamail) but as far as I know none exists for using the 
serial port of the palm. The library is just acting as a transport layer 
to move data between the two devices. Your application does not need 
changing, as it will still recieve 
sysAppLaunchCmdExgAskUser/sysAppLaunchCmdExgReceiveData launch commands 
no matter which library is used to transport the data. At the remote end 
the exchange library tells the exchange manager that it has data, and 
the exchange manager will send the approprate launch codes the the 
application to recieve that data.



the sequance of events is:-
1) Sending application inialises ExgSocket, optionaly specifying which 
library to use

2) Sending application calls ExgPut
2a) Sending exchange manager looks for registed libray, and prompts if 
more that one is registed for the requested scheme (i.e. "_send")
2b) Sending Exchange mananger calls ExgLibPut for selected exchange library
2c) Sending Exchange library initialtes connection to remote end

3) Sending app calls ExgSend
3a) Sending Exchange manager calls ExgLibSend for selected exchange library
3b) Sending Exchange libray sends data to remote end
3c) Recieving Exchange library saves data for later use

4) Sending app calls ExgDisconnect
4a) Sending Exchange manager calls ExgLibDisconect for selected exchange 
library
4b) Sending Exchange library Disconects from remote end and cleans up

5) Recieving Exchange Library calls ExgNotifyReceive
5a) Recieveing Exchange manager sends 
sysAppLaunchCmdExgAskUser/sysAppLaunchCmdExgReceiveData  to registered 
application.
