Reading data from Serial / USB port
Hi All
I have a piece of test equipment that can output data via a serial cable. I have a USB adaptor and the right serial cable, but the original software
doesn't seem to be available.
Is there any way I can download the data onto my PC into an ASCII / text file (I can probably work with the data by writing a bit of code / Word
macro)?
The format of the data is as follows:
Baud Rate 9600
Start Bits 1
Stop Bits 2
Data Bits 8
No parity
Ta in advance
Wyn

If you're using WinXP you could use HyperTerminal to open a text based COM link to the bit of kit. Hyperterminal disappeared from Win7 so I use
a very good free equivalent 'CoolTerm'.

Hope this helps.

In a DOS box something like
cat COM1:9600,8,2,1 >data.txt
should do it. Google that parameters as I can't remember it exactly off the top of my head.

puTTY will do it too. It's usually used for talking to Linux boxes, but it has an option to work on the serial port too.
Free download and only a few kB: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Thanks guys - loads of options!
My bit of test equipment is away for calibration - I'll give your suggestions a try when I get it back.
Ta very much!

Sorry to poach a subject, but can any of those options work in 'transparent' mode? I have a similar set up but I actually have the
software, and I'd like to 'listen in' on the conversation without the software knowing that I am?

The problem here is going to be which side of the conversation do you want to listen to?
If you had a PC with two serial ports, you could knock up a special cable that looped the data lines through the ports, then run two instances of
putty (or whichever program you use) and turn on local echo to make sure the characters get pushed through to the end device. That would probably do
what you wanted.

OP: My current favourite for talking to serial ports under windows is Tera Term Pro:

Slimy, VSPE has an option to let you open the same serial port twice with two different options (I've not tried that option, but I guess it
might be able to let you snoop?):
