$ stty -crtscts -F /dev/ttyS0

Table 4-2. stty Flags Most Relevant to Configuring Serial Devices

   
   Flags    Description
   N    

Set the line speed to N bits per second.

Enable/Disable hardware handshaking.

Enable/Disable XON/XOFF flow control.

Enable/Disable modem control signals such as DTR/DTS and DCD. This is necessary if you are using a "three wire" serial cable because it does not supply these signals.

Set number of data bits to 5, 6, 7, or 8, respectively.

Enable odd parity. Disabling this flag enables even parity.

Enable parity checking. When this flag is negated, no parity is used.

Enable use of two stop bits per character. When this flag is negated, one stop bit per character is used.

Enable/Disable echoing of received characters back to sender.

The next example combines some of these flags and sets the ttyS0 device to 19,200 bps, 8 data bits, no parity, and hardware handshaking with echo disabled:

$ stty 19200 cs8 -parenb crtscts -echo -F /dev/ttyS0
