OK(0) S-Registers S Registers are 1 byte, volatile registers used to store configuration data. They are reset to the default state whenever modem emulation is enabled, or the ATZ/AT&F command is received. They can be saved to flash memory with the AT&W command. When the port is opened, the saved parameters are applied to the port.

It is designed to be connected to another DTE device via RJ-11 cable.The RI (Ring Indicator) signal does not have a corresponding outgoing signal so it is not supported. Specifically, the DTR, DSR and DCD signals should be crossed with the device as follows: Device RJ-11 IP Gateway DCD,DSR DTR DTR DCD,DSR To emulate a modem properly, the Host RJ-11 IP Gateway does the following: Mode Modem DCD Settings Behavior Command/Data Always on (&C0) DTR is asserted Command/Data Follow connection (&C1) DTR is asserted only when TCP/IP connection is present and has been accepted via ATA or auto- answer. DTR is de-asserted when connection is lost The device server monitors its DCD signal in order to detect changes in the device's DTR signal. The following behaviors occur on loss of DCD only. Mode Modem DTR Settings Response to loss of DCD Offline AT&D0 Ignore Offline AT&D1 Ignore Offline AT&D2 Ignore Online AT&D0 Ignore Online AT&D1 Drop to command mode, preserving connection Online AT&D2 Drop to command mode, terminating any connection Phone Numbers The “phone number” used in an outgoing connection for an “ATD” command may be a real phone number that is translated to an IP/port pair (see Phone Number Translation) or it consists of an IP address and optional port number. All leading non-numeric characters (such as the T or P dial modifiers) are ignored. A number of formats are accepted for the “IP” phone number. Format Example Notes Dotted decimal a.b.c.d or 192.168.1.1 Numbers are from 0 to 255 Comma decimal a,b,c,d or 192,168,1,1 For programs that don't allow dots in phone numbers Fixed format aaabbbcccddd or 192168001001 12 digit IP address, each number is three decimal digits with leading zeroes Optional port number :xxxxx Decimal TCP port number from 0..65535 •If no phone number (IP address) is specified, the Destination IP Address configured for the port is used. •If no port number is specified, the Destination TCP Port configured for the port is used. •The source port for the TCP connection follows the Source TCP Port configured for the port. Port Settings Most of the serial port settings (like baud rate) are controlled by the configured port settings on the device server. Modem emulation does not support changing these from AT commands.
