Hi,

If RThreshold is 1 then the OnComm should fire repeatedly and you should be able to build up the complete message eg

IF THIS.CommEvent = 2
IF THIS.InBufferCount>0
lcString =  lcString+THIS.Input
If SomeCheckToSeeIflcStringIsComplete()
  * Process the message
.......

But if, as you say, OnComm is NOT firing repeatedly then it's hard to know what the problem might be. This link has a VFP example which might help:http://support.microsoft.com/kb/q154741/

Best,
Viv
