I am attempting to login from a Linux client to a set top box running Linux via a USB to serial cable. When I power on the device, I can see the init messages scroll past, and I get to the login prompt, like this:
(none) login:
but I cannot login. The cursor stops flashing as if it is receiving input, but there is no response.
My serial port setup is:
Device: /dev/ttyUSB0
Bps: 115200 8N1
Hardware Flow Control: Yes
Software Flow Control: No
Any help would be greatly appreciated!
