Solved Serial spy: has anybody already made somehing like this?
-
Hi All,
I'm debugging a device that is connected via a serial port to my PC. I'm now using "Advanced Serial Port Monitor" from aggsoft.com. I am using it in dual port mode, where it listens to 2 serial ports. The Rx wires from the two comm channels are wired into the Rx and the Tx line that are used to talk to the device. In total I use 3 serial ports.
I am looking for an open source alternative, but i could not find one. Does anybody know such a program?
Cheers,

Hi
im using
http://com0com.sourceforge.net/
to allow to me to bridge virtual comports and in that way
let one app to send to other app on same pc. (like a virtual serial wire)
( this is due to pc having 1 serial and i got tired of carry USB serials adapters around)
Im not sure you need this, but no hurt in mention it :)And for serial app, i use
https://sourceforge.net/projects/realterm/Not sure if relterm can do what you want ( i not sure what dual mode covers for SPM) but in later version realterm has monitoring mode for spying.

com0com is a good shout actually but I don't think it would allow you to "spy" on a physical serial port - for virtual-to-virtual ports, its ideal. I have read somewhere on stackoverflow where someone seems to indicate that it can hook up to a physical port but I've not been able to recreate that.
I'm about to embark on trying to write a nice Qt wrapper to encapsulate the com0com stuff but sometimes, only USB-to-serial ports will do in a world full of archaic sensors!

I use this USB to 4 serial port converter:

Hi all,
I have written a program that can monitor 2 serial ports, and dump it onto the screen and into a file. It's tested on windows, but I would be surprised if it didn't work on all other platforms supported by Qt.
