Hi,

I wrote a small test program that would communicate VBA
with an external microprocessor via the serial port. I'm
using MSComm. This code works fine when I send it out in
this fashion:

MSComm.Output = "123456"

However, when I use a variable for the output, I get an
error stating it's an invalid property value:

Dim v as string
v = "123456"
MSComm.Output = v

How is this different than what I did previously? I don't
know what to do. I tried using Str(v), but that doesn't
work either. Help! Thanks.
