/dev/ttyUSB0 one way connection

#1 Post by KenHorse »

I've been fighting a USB > serial converter on a Debian Stretch machine (Prolific PL2303)

dmseg confirms the adapter is connected to /dev/ttyUSB0 and I can connect (via minicom) to it no problem. However, it only seems to work on incoming data but won't send anything out

For example:

cat /dev/ttyUSB0 reads data coming in just fine but echo "test" >/dev/ttyUSB0 doesn't send anything out

Same results within minicom

No permission issues as I'm doing this as root and I've checked everything I can think of with stty

Thoughts?
