4.28.6 Selecting the serial flow control scheme

The ‘Flow control’ box allows you to choose what type of flow control checking is used on the serial line. The settings are:

• ‘None’: no flow control is done. Data may be lost if either side attempts to send faster than the serial line permits.
• ‘XON/XOFF’: flow control is done by sending XON and XOFF characters within the data stream.
• ‘RTS/CTS’: flow control is done using the RTS and CTS wires on the serial line.
• ‘DSR/DTR’: flow control is done using the DSR and DTR wires on the serial line.
