Open Socket Question

[Phil Davis]

Hi Dave,

I don't have time to write sample code right now, but one approach would be:

- set the socketTimeoutInterval to something reasonable
- make a 'connectToServerApp' handler that opens one socket, using the 
params passed to it by 'startClient'
- let 'StartClient' do this once for each line in your server list:
      send ("connectToServerApp" && tOneIpAddress) to stack in 0 ticks
- make a 'socketTimeout' handler than resends the 'connectToServerApp' 
cmd (with params) to stack in x ticks
- make a 'socketError' that notifies you of connection failures
- when the openSockets contains all the addresses in your original list, 
you're done
