Monitoring ASCII Stings between Two Serial Devices
Posted: Sun Mar 16, 2014 9:50 am
I Love CoolTerm. Mac and Windows.
I have a home automation controller with a serial port that connects to a third party serial device for lighting control.
I've used CoolTerm to send and receive strings from the automation controller with success. All of the ASCII is correct.
I've also used it to interface to the Lighting Controller to send and receive ASCII strings and that works correctly as well.
The problem is, when connected, the two systems are not playing well and I need observe the communication between both devices to determine where the fault is. I need to observe the response packets that the 3rd party device sends back in response to commands from the automation controller and I also need to observe the command packets sent from the automation controller *when connected* to the 3rd party Lighting Controller.
Hoping one of you serial-killers might have some ideas because I'm certain CoolTerm can't loop through a COM Port to a 2nd port.
Thanks
Peter
