Description
Hook Control. Note that in some countries H1 will be limited by a timer (i.e., the maximum
time off-hook without a carrier negotiation). In those cases, S7 or a hardcoded constant
will be used for the upper limit of this timer.
0: Modem goes on-hook (default).
1: Modem goes off-hook.
Result Codes:
OK n=0, 1
ERROR Otherwise
Request ID Information. In desplays specific product information about the modem.
0: Returns default speed and controller firmware version, same as I3.
1: Calculates ROM checksum and displays it on the DTE (ie. F15D).
2: Performs a ROM check and calculates and verifies the checksum displaying OK or
ERROR.
3: Returns the default speed and the controller firmware version, same as I0.
4: Returns firmware version for data pump (ie. 57).

2: The speaker is always on when modem is off-hook.
3: The speaker is on until the carrier is detected, except while dialing.
Modulation Handshake. Nn controls whether or not the local modem performs a negotiated
handshake at connection time with the remote modem when the communication speed of
the two modems is different. The N command affects the initial physical layer connection
only. It does not affect subsequent speed changes made by V.32bis or MNP class 10
operation.
0: When originating or answering, this is for handshake only at the communication
standard specified by S37 and the ATB command.
1: When originating or answering, begin the handshake only at the communication
standard specified by S37 and the ATB command. During handshake, fallback to a
lower speed may occur (default).
