Addendum to Compaq Armada 1500 Maintenance and Service Guide Table C-1, Modem Commands, Continued Command Description Hn 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 In 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). 5: Returns the board ID: software version, hardware version, and country ID. Birdie Code Default Country Country Country ID Configuration Support Code(zz) String (ccc) -001 North America 19 NA -002 Japan 10 JPN -003 APD 14 SNG 9: Returns 2 or 3 character country ID string and 1 to 2 character version of country parameter table. (ie. ccc Ver. v). Ln Monitor Speaker Volume. Ln sets the speaker volume to low, medium, or high. 0: Selects low volume. 1: Selects low volume. 2: Selects medium volume (default). 3: Selects high volume. Mn Monitor Speaker Mode. Mn turns the speaker on or off. 0: The speaker is off 1: The speaker is on until the modem detects the carrier signal (default) 2: The speaker is always on when modem is off-hook. 3: The speaker is on until the carrier is detected, except while dialing. Nn 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). Continued 20 Addendum 255318-001 to Guide 284820-001
