Re: [gentoo-user] [OT] laptop desktop serial connection don't work on one direction

Is there some inittab setting that's different on your laptop? -- Sent from my HP TouchPad  On Nov 5, 2011 2:21 AM, Kfir Lavi <lavi.kfir@×××××.com> wrote:   Hi all, I have a problem connecting my laptop to my server at home with a serial cable. I have cable end for /dev/ttyS0 and 2 cable ends for /dev/ttyUSB0. This lets me test the connection between all serial outputs. 

Desktop1-minicom <-> Desktop2-minicomworks with all connections, i.e ttyUSB0 <-> ttyUSB0, or ttyS0 <-> ttyUSB0 and viseversa. So when connecting 2 desktop computers everything works as expected.

The problem:When I connect my laptop to any of those desktops, I get just one way connection!If I swap the sides of the cable, the one way connection switch side.The laptop doesn't have ttyS0, so it have to be connected via ttyUSB0

When I swap sides, it is just between two usb dongles. The usb dongles are PL2303 both sides. Settings of minicom is 38400 8n1  Hardware Flow Control=OFFLaptop setserial:setserial -a /dev/ttyUSB0

I'm not sure what to do next.Any help will be appreciated, Thanks,Kfir
