Thanks for the fast reply Viv.
The OnComm fires only once, when we push the export button on the machine.
In Hyperterminal, we get all data instantly.
What do you recommend?
Thanks

>The ONCOMM event fires for many reasons. You should not expect that ALL (or even any) data has been received. Accumulate the contents of buffer untill you have a complete 'message'
