Table 10-1: Serial Port
Command Description
Startup Mode Default 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 into a terminal application connected to the serial port within 5 seconds changes
the mode to normal (AT command) mode. See also S53 to set the port for UDP .
• SLIP
• PPP
• UDP
• TCP
• PassThru
• DM mode
• PinPoint MDT
• Reliable UDP
• UDP Multicast
Configure Serial Port Format: [speed],[data bits][parity][stop bits]
Valid speeds are 300-115200, data bits: 7 or 8, parity: O,E,N,M, stop bits: 1,1.5,2
Flow Control Serial port flow control setting.
• No flow control is being used.
• RTS/CTS hardware flow control is being used.
• Transparent software flow control. Uses escaped XON and XOFF for flow control.
XON and XOFF characters in data stream are escaped with the @ character (0x40).
@ in data is sent as @@.
DB9 Serial Echo Toggle AT command echo mode.
• Echo Off.
• Echo On.
With more than one connection types (serial, and Telnet, and USB/Serial) the echo
command is set differently on each interface.
Data Forwarding
Timeout
Data forwarding idle time-out. If set to 0, a forwarding time-out of 10ms is used. Used in
UDP or TCP PAD mode.
• tenths of a second
Data Forwarding
Character
PAD data forwarding character. ASCII code of character that will cause data to be
forwarded. Used in UDP or TCP PAD mode.
No forwarding character.
Device Port Default Destination Port to send TCP/UDP communications to
Destination Port Default Destination Port to send TCP/UDP communications to.
Destination Address IP address to send TCP/UDP communication to.
Default Dial Code Default Dial Data Mode.
Assert DSR Assert DSR always, or when the device is in a data mode (UDP, TCP, etc.) or when the
device is in network coverage.
