Serial/terminal access

Is there a way to interact with a serial terminal in hass.io? I am trying to check output on /dev/ttyUSB0 for integration with an Alarmdecoder usb and an older Ademco panel. I see minicom in in /usr/bin but it cannot find /dev/ttyUSB0. The port is listed as connected in ‘hassio host hardware’ and I see it in dmesg when pluged/unplugged. Admittedly I am not all that familiar with the nuances of docker.
