The result would be the serial terminal seeing echo of what you type if it works, or nothing if it fails. If you wish to test a port you can use loopback to have the port talk to itself. Note that if two ports are using different settings, then you will either get no output or output will be corrupt. Optionally, if hardware flow control is used (not used in serial console, but perhaps used for your app):.If you use this on a system with ttyUSB0 as the port, and if the port is set to 115200 8N1: gtkterm -b 8 -t 1 -s 115200 -p /dev/ttyUSB0 I’ll recommend testing first with gtkterm since it is purely a serial console: sudo apt-get install gtkterm If modem init strings are being sent there is no telling what the result would be. “Not connected” could be referring to a telephone PPP or SLIP connection and not to the UART. Those modems were not only serial UARTs, they also had “AT” command sets…short commands which configured the modem itself and not just the UART. Realize that minicom came from a day when people used telephone modems most of the time.
