Com ports

[Blade]

I have a question about how I tell what com ports (/dev/tty?? ) are in use on the Hometroller SEL
Can we run a command somewhere to list the /dev/ttyS? ports available similar to the RPi?

Yup; linux is linux.

SSH to your SEL to look see. Note that it is not HS3 that sets the com port rather it's the operating system (well like in Windows). Here are 8 serial ports configured via one Digi USB to 8 serial port box.

pete@ics-HS3:/dev$ ls ttyUSB*
ttyUSB0 ttyUSB1 ttyUSB2 ttyUSB3 ttyUSB4 ttyUSB5 ttyUSB6 ttyUSB7
pete@ics-HS3:/dev$

You can see what specific USB to serial devices you utlize by typing lsusb

pete@ics-HS3:~$ lsusb
