For starters, its ttySx NOT ttysx: bash-2.03$ setserial /dev/ttys0 /dev/ttys0: Input/output error bash-2.03$ setserial /dev/ttyS0 /dev/ttyS0: Permission denied bash-2.03$ sudo setserial /dev/ttyS0 Password: /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 For doing a straight echo like that, and expecting something at the other end, you need to setup baud rates etc. Generally you set something like this up in iniitab, to watch the serial port with a getty, then when the terminal program connects you get a login prompt: # Serial lines #s1:12345:respawn:/sbin/mingetty -L 9600 ttyR0 vt100 #s2:12345:respawn:/sbin/agetty 19200 ttyS1 vt100 Just uncomment (remove the #) and set the rates/terminal type appropriately. Now if you are trying to go the other way from the Linux box to the Windows box, I'm not sure what you hope to be able to do once you're connected. Not much, unless you're running some BBS software on the Windows box. In that case, use minicom on the Linux end.
