Com Port

Hi all;

What simple DOS based (or windows if you may) commands can i run to see if their is a device connected to acom port?

Basicly i know there will be a connection on the com port, but the device will not return anything in a normal mannor (it is a pin pad) but what i want to be able to check is if the cable that conencts teh device is working properly.

A ping or something like that would be brilliant,

Any one got any ideas?

Thanks all!

errrrr… I have a vague memory of opening a dos window, and tapping in " Mode Com1: "
or something similar.

wasn’t it something like
tty com1
mode: 8,n,1,p
<other commands>
