>If your are willing to try MSCOMM32.OCX and the VFPCOM utility ...

PMFJI -

yep, the MSCOMM32.OCX is a good way to go, but you don't really
need the VFPCOM utility to bind events, because the MSCOMM32
control already has an event that fires every time it receives
a character. that event is the "OnComm" event. all you need
to do is to react to that event on every received character
and buffer (them) somewhere, and when your received character
is CR and/or LF, send your entire buffer to the textbox, and
clear the buffer. no need for any looping to check the MSCOMM32
control status either, since the event fires asynchronously.
