Thanks gentlemen, all good information.

Of course the only real method of achieving success is to put the 'hands on' and work my way through it, it's a background task and will take time but I'm sure the fruits of success will be very sweet.

@Richard
Your assumptions are correct mate, however each of the incoming streams end with CRLF and also have distinct start headers (as mentioned a bit like GPS NMEA strings) so there is hope. If you don't have any Richard I can post a couple of the Q43 to you when I receive samples because I'm sure to ask for help at some stage (same address?) - you have my email address from before however please change the gmail to yahoo, otherwise the same.

The print sharers would have only worked with handshaking I reckon.

Cheers,
Bill in Perth
