Title: Multimeter to check for data? Post by: SAT (aka GANDHI) on September 30, 2008, 09:49:21 PM Hi, I'm trying to send data from an MSDOS application down an RS232 lead to an LED display. Can I use a mutlimeter to check the presence of data down the cable? Thanks in advance. Paul Title: Re: Multimeter to check for data?

Grab an RS-232 "breakout box" with LED and you'll see the LEDs flicker when the data is flowing. Title: Re: Multimeter to check for data?
