AT Command Reference Manual

Hn - Disconnect (Hang-Up)
This command initiates a hang up sequence.
This command may not be available for some countries due to PTT restrictions.
H0 The modem will release the line if the modem is currently on-line, and will terminate any test
(AT&T) that is in progress. Country specific, modulation specific, and error correction protocol
specific (S38) processing is handled outside of the H0 command.
H1 If on-hook, the modem will go off-hook and enter command mode. For US models, the modem
will remain off-hook. For W-class models, the modem will return on-hook after a period of time
determined by S7.
Result Codes:
OK n = 0 or 1.
ERROR Otherwise.
In - Identification
The modem reports to the DTE the requested result according to the command parameter.
I0 Reports product code. Example: 28800
I1 Calculates the ROM checksum and reports the least significant byte of the checksum in decimal
(see firmware release notes). Reports 255 if the prestored checksum value is FFh.
I2 Calculates the ROM checksum and compares it with the prestored checksum. Reports "OK" if the
calculated checksum equals the prestored checksum or if the prestored checksum value is FFh;
otherwise reports “ERROR”.
I3 Reports the firmware version (F), basic model (e.g.,V34), application code (A), and interface type
code (I) typically in the form VF.FFF-V34_AI. The application codes are: D = Desktop, L = Low
Power (PCMCIA). The interface type codes are: S = Serial, P = Parallel. Example: V1.400-
V34_DS
Note: If RPI+ is supported, “ROCKWELL RPI (TM)” is appended.
I4 Reports OEM defined identifier string in either Hayes-compatible binary format (default) or ASCII
format (selectable by ConfigurACE). Example: RC288ACi (ASCII)
I5 Reports Country Code parameter. Example: 022
I6 Reports modem data pump model and internal code revision. Example: RC288DPi Rev 05BA
I7 Reports the DAA code resulting from MCU interrogation of the DAA for auto DAA recognition.
Examples: 000 for US or Canada, 016 for Japan, 033 for Belgium, 034 for Finland, 035 for
France, 037 for Italy, 038 for Netherlands, 039 for Sweden, 040 for Switzerland, and 041 for UK.
Result Codes:
OK n = 0 to 7.
ERROR Otherwise.
Ln - Speaker Volume
The modem sets the speaker volume control according to the parameter supplied. The parameter value, if valid, is written to
S22 bits 0 and 1.
L0 Low volume.
L1 Low volume. (Default.)
L2 Medium volume.
L3 High volume.
Result Codes:
OK n = 0 to 3.
ERROR Otherwise.
