I have cable end for /dev/ttyS0 and 2 cable ends for /dev/ttyUSB0. This lets me test the connection between all serial outputs.

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 bet= ween all serial outputs.
Desktop1-minicom <-> Desktop2-minicom
works 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 ge= t 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 t= o be connected via ttyUSB0
When I swap sides, it is just between two usb dongles.

The usb dong= les are PL2303 both sides.
