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-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 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=OFF Laptop setserial: setserial -a /dev/ttyUSB0 /dev/ttyUSB0, Line 0, UART: 16654, Port: 0x0000, IRQ: 0 Baud_base: 460800, close_delay: 0, divisor: 0 closing_wait: infinte Flags: spd_normal Desktop1 setserial: setserial -a /dev/ttyS0 /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test setserial -a /dev/ttyUSB0 /dev/ttyUSB0, Line 0, UART: 16654, Port: 0x0000, IRQ: 0 Baud_base: 460800, close_delay: 0, divisor: 0 closing_wait: infinte Flags: spd_normal I tried to add the skip_test but this seems to be not working. I'm not sure what to do next. Any help will be appreciated, Thanks, Kfir
