I have the following scenario: a laptop running Windows XP, connected to a meter through its serial port.

I need to read/write to this serial port from a remote computer (running windows 7). I also should be able to send some serial-port signals, such as a RTS.

Is there any software that gives me these capabilities?

Out of curiosity, why not RDP to the laptop? – Iszi May 10 '11 at 19:25
I've tried. It does not seems to make the serial port available. – Fernando May 10 '11 at 19:33
I meant, why not RDP to the laptop and run whatever application you need on the laptop? It may be the long way around, but it should do the job for you. – Iszi May 10 '11 at 19:42
I need to code a driver for the meter communication and I can't run my tools on the laptop. – Fernando May 10 '11 at 19:47

This should work:

The page is in spanish but you can use Google Translate. Basically is a c# app (source & compiled)

It won't send the RTS signal, just the data. I need to be able to remotely activate the RTS pin. – Fernando May 11 '11 at 12:48

use hterm

I know it is a german site, but you just need to click the download version. The program itself is english. Once you connected the right port you can set the RTS via a button in the lower half of the GUI. Works for me
