Working with the M111

Connecting serial devices

Data bits

Number of data bits.

Parity bit

Sets the parity.

Stop bits

Number of stop bits.

Baud rate

Baud rate in bps.

Software flow control

None: The M111 does not provide flow control. Instead, flow control is performed end- to-end by the remote TCP device and the locally connected serial device.

XON/XOFF: Flow control is performed locally using XON/XOFF. In this case, the attached serial device must also support software flow control.

Hardware flow control

None: The M111 does not provide flow control. Instead, flow performed end-to-end by the remote TCP device and the locally connected serial device.

RTS/CTS: Flow control is performed locally using RTS (Request To Send)/CTS (Clear To Send). In this case, the attached serial device must also support hardware flow control.

Max receive buffer

Receive buffer size in bytes. If the buffer becomes full, data is discarded until space can be freed up.

Port controlDrop wireless link when port 1 is connected

This feature can be used in cases where the remote TCP device is accessible via both Port 1 and the wireless link. When enabled, it automatically switches the TCP connection based on the status of the Port 1 connection:

When Port 1 is connected to an Ethernet network, the M111 drops the wireless connection and sends all traffic via Port 1.

When Port 1 is disconnected from the Ethernet network, the M111 attempts to establish a wireless connection via the appropriate station profile. Traffic is then sent on the wireless link.

Note

To use this feature, Port 1 and the Wireless port must connect the M111 to the same subnet.

TCP connection status

This table lists status information for the TCP connection.

State

Indicates the state of the TCP connection. Possible values are:

3-26
