I didn't found any similar case so I ask you the question.
I try to install pfSense on an APU, I connect a Serial Cable (USB to Serial + NullModem) and launch a screen : screen /dev/ttyUSB0 115200
I start the APU and I see on my serial terminal all the information, no problem.
But when I try to send a command (any charactere) it never be send. I can't sent any information to the APU, who wait...
Anybody know if I made a mistake or if I have to check something ? (I didn't have an other cable to check, but if I can read, I suppose it work...)
