I need to verify what's being output on an RS232 port of an appliance that's running proprietary software (e.g. NOT Windows or Linux). The port is sending data to a target app on another appliance, but I need to verify/log the actual data raw outside of the appliances. Would appreciate a recommendation on process/software to attach to the physical sending port (I have a straight through RS232 cable) and grab sample output of that port.
