I have an Arduino with a temperature module and an APC220 rf module
attached. I have another APC220 connected to my PC through a USB/
serial converter on Com 7. If I point the serial monitor to Com 7, I
see the temperature displayed continuously. I have tried three
terminal emulators (Putty, Indigo, and Realterm), pointed them to Com
7 and see no data. I know they are looking at Com 7 because if I point
the Arduino IDE terminal to 7 then try to use the others I get the
message "Com 7 in use". What I am trying to do is monitor the signal
to make sure it is still working, while programming another Arduino
with an APC220 and a LCD, which I have so far not been able to
display the data on. What is different about the IDE's terminal? I am
using 9600 baud, no parity everywhere.

Check the flow control settings on both your device and in the terminal

emulator.
Make sure they are both using the same flow control options or that
flow control is disabled in both the device and the emulator.

program. Your only options are
parity (odd/even/disable), and baud rate. I tried all 4 choices in the
drop down box for flow control in Putty,
none worked.

The device side does not even mention flow control in the setup

Do you have access to a Linux box with C-Kermit installed ?

This is my usual setup for diagnosing such problems and it works well
for me.

This of course assumes your USB to serial converter is supported under

Linux, but a Google search should reveal that quickly enough (assuming
your converter is sufficiently mainstream).
