Craig,
Mscomm clears its own buffer whenever .input is done. To see if the stream is ended or full, look at the .inbuffercount to see if it is stable (enough) or big enough to do the .input into your listbox.

>I am attempting to utilize the Microsoft Communication Ole (MSCOMM32) in VFP 5.0. I am able to open the port and set the parameters and it appears to be working, but I don't know for sure. When I send a character stream to my computer's comm port and perform a receive request [i.e. frmMyForm.lstMyListBox.AddListItem(frmMyForm.oComm.input)] I never see the character stream that was sent. Preferably I want to automatically see (in a list box, window, screen, etc.) what was sent to the to the comm port every time a new stream is received.
