Status Field Description
Serial Reserved by
External Application
Indicates whether the serial port has been reserved by an external application.
Serial Port Mode Default power-up mode for the serial port: When the AirLink device is power-cycled, the
serial port enters the mode specified by this command after 5 seconds. On startup, typing
ATMD0 within 5 seconds changes the mode to Normal (AT command) mode.
TCP Auto Answer This parameter determines how the AirLink device responds to an incoming TCP
connection request. The AirLink device remains in AT Command mode until a connection
request is received. DTR must be asserted (S211=1 or &D0) and the device must be set for
a successful TCP connection. The AirLink device will send a “RING” string to the host. A
“CONNECT” sent to the host indicates acknowledgement of the connection request and the
TCP session is established.
• Off (Default)
• On
• Use Telnet server mode on TCP connections
With a Telnet connection, overrides the client's default echo and allows the server on the
host port to perform the echo. CRLF sequences from the telnet client will also be edited to
simply pass CRs to the server on the host port.
UDP Auto Answer Enables UDP auto answer (half-open) mode.
• Normal mode
• Enable UDP auto answer mode
Serial bytes sent Number of bytes sent over serial port to host.
Serial bytes received Number of bytes received over serial port from host.
