I want to be able to view some data on an output device. I saw an
example in the Metrowerks CodeWarrior and it outputs to the SCIO. I
tried doing that and I am able to see data on the transmit pin of the
Serial connector (P1). How do I get that to talk with my computer's
hyperterminal, so that I can see the data on the screen and not on the
scope? The hyperterminal keeps saying "Unable to open COM1"

Can Hyperterminal open another device on COM1?

I don't know. But placing a scope on the Transmit pin of the UART
showed data and I fabricated a null modem config between that and the
COM1. Since Hyperterminal gave me an option of reading data on COM1, I
assumed that this data should be captured by Hyperterminal and
displayed. But I all I get is "Unable to open COM1". I am now trying
to eliminiate a hardware/software problem on the computer by trying
this software:

===============================================When you figure out which com port is working, use the 'short pins 2 to 3
with your car keys' trick to make sure the pc terminal hw and sw is working.

But don't forget to set the PROTOCOL to none - otherwise it will wait
for CTS/RTS handshaking. In my version of Hypercom you will find it
under FILE - Properties - connect to - Configure

It turns out that the Transmit and Receive pins coming out of the board
are not the same as it should be on an RS232 connector.I had to switch
the wires around in my null modem cable. Hyperterminal still didn't
work, but PortMon software was able to capture data. Also, if I created
a project using the board stationery, CodeWarrior itself opens a
Terminal and spits out the data!
