All Implemented Interfaces:

Connection, InputConnection, OutputConnection, StreamConnection

public class Connection

extends BaseConnection

implements StreamConnection

The comm connection. This allows a UART to be opened using the format:

Connector.open("comm://[;param[&optional params...]]");

For example:

Connector.open("comm://1;speed=38400&bits=6&stop=1&parity=none") opens a port at 38400 bits per second, 6 bits, 1 stop bit and no parity.

The available parameters are:

• speed - this is the speed in bits per second of the connection
• bits - the number of bits to use
• stop - the number of stop bits to use
• parity - the parity. either odd, even or none
• flow - either off, sw or hw
