Thanks for the code snippet. It works great!

BTW, I couldn't find any documentation for any of the comm functions in FoxTools in VFP help. Any idea where they are?

opencomm  = RegFn("OpenComm", "CII", "I",'User.exe')
writecomm = RegFn("WriteComm", "ICI", "I",'User.exe')
closecomm = RegFn("CloseComm", "I", "I",'User.exe')

lnport = CallFn(OpenComm,lccomport, 100, 100)
