Google is your friend - the tera term pro home page is the first hit when
googling for "tera term pro":

I found I had a distribution from 1998 tucked away on my drive,
and it looks good.  Do you know offhand where the source is to be
found?  My only wishes so far are that it had a single page
printable helpfile/manual and that the 'monitor communications'
ability had been implemented.

Tera Term is one of these rare programs which does everything the author
wanted it to do, and is (as far as I know) bug-free.  Thus it has not
changed in 5 years, simply because it does not need to be changed.  As far
as I have heard, it works fine in all 32-bit windows (and there is a win3.1
version too).  Since it is open source, a few others have made extensions
for ssh and webby stuff, but the serial port stuff is the same.

Thanks all for your replies. As is, my first sample code printed a
character 'x' in Hyperterminal, thus everything seemed fine in baud
rate settings, register settings and so on. Every other example I've
tried has worked like charm every time. But, reading your suggestions
led me to try with Hyperterminal once more, with flow control = none.
And what do you know, it worked!!

I'll try Tera Term next time! But a brief search for Tera Term led me
to think it wasn't supported by Win XP, but I've just hit another site
which seems to support TT Pro for Win XP.

Well, thanks for now.

No, not if you configure it for Flow Control = none.

Agreed. Minicom even nicer.

I'd second that as a first step (!). HyperTerminal is not very happy unless
all the control lines are connected and even then it gets things wrong.
TeraTerm is much easier to use, has macros and doesn't pester you with
dialog boxes.

Without digging up my examples (I use MSP430 a lot, but I wrote the UART 
code a long time ago), why not try it in stages:

(0) Is HyperTerminal broken? I had this recently when playing with an 
ez80. I used TeraTerm instead, and all was fine.

(1) get rid of the interrupt. Loop transmitting a character in main(). 
Does the output appear?

(2) Once (1) works, wait to receive a character in main and echo it. Use 
the scope to check that the character actually reaches the pin.

(3) Then put the lot back in interrupt. Make it flash an LED or an 
output you can scope when it goes through the ISR.

Hi!

I am trying to get the TX/RX echo example program to work on an Olimex
Easyweb II MSP430 starter kit. I am able to receive character on the
host PC using HyperTerminal to monitor the serial connection (TX on
embedded microcontroller). However, it does not receive any characters
sent from the terminal program, and I am just about out of options on
how to debug this problem. Anyone that could provide any help? I post
my code (small changes from TI example to adapt to other oscillator
frequency).

Thanks, regards
