The serial port type determines the protocol used on the serial port. Possible values are:

• dummyDUMMY: serial interface presented to emulator is not connected.
• socket: the port is set to TCP raw mode.
• telnet: the port supports the telnet protocol.
• pty: indicates that the emulated serial line is connected to a Linux pseudo-terminal.
• tty: emulated serial line is connected to physical hardware (serial hardware must be supported by Linux).
• RFC2217: emulatied serial line is connected to a serial line server across the IP network.

Each port is mapped to a TCP socket on the emulator host or to a physical line. This parameter defines the TCP port used, the name of the physical device, or the port and address of a serial line server. A port number must be unique among all active port numbers on the host system.

A TCP port is specified as "<where-to-listen>:<portnumber>". It requires a port type of socket or telnet.

Default values (listening on all interfaces):

• ":30000" for line 1
• ":30002" for line 2

To restrict console connections to certain host interfaces or host IP addresses, set where-to-listen to the respective interface name or IP address. The settings lo:<portnumber> and <portnumber> (without the colon) are equivalent.

A physical device is specified as "<device-file>". It requires a port type of device.

Example:

• "/dev/ttyS0"
• "/dev/ttyUSB0"

A serial line server is specified as "<ip-address>:<port>".
