SPORTSTER 14,400 APPENDIX C. ALPHABETICAL COMMAND SUMMARY Additional command summaries are on the bottom panel of the modem and in the Quick-Reference Card. REQUIREMENTS 1.Type commands in either upper or lower case, not a combination. 2.All commands except A/ and +++ are preceded by the AT prefix and are executed with the Enter/Carriage Return key (). 3.Command length = 40 characters maximum. The modem doesn't count the AT prefix, Carriage Return character, or spaces. In a dial string, it counts but doesn't act on punctuation such as hyphens and parentheses. 4.A missing numeric parameter is assumed to be zero, as in the command to hang up: ATH is the equiv alent of ATH0 . BASIC COMMAND SET & See the Extended Command Summary that follows this Basic Set. A Force Answer mode/Manual Answer. The modem goes off hook in Answer mode when it detects a ring on the phone line, and sends an answer tone. If it fails to detect a carrier signal from a calling modem within 60 seconds, it hangs up and Manual Answer mode is cancelled. Pressing any key after the modem goes off hook aborts the manual answer operation and hangs up the modem. A/ Re-execute the last issued command. Used to redial. A/ doesn't take the AT prefix or a Carriage Return. Any key Abort current connection attempt resulting from an issued D or A command. AT Attention: lets the modem know commands are being issued to it. Must precede all other commands except A/ and +++. Bn CCITT/Bell answer sequence. B0 CCITT V.25 answer sequence (Default). Required to connect from 14.4K down to 4800 bps. Also required for modems answering overseas calls at 1200 and 2400 bps. B1 Bell answer tone, United States and Canada. Dn Go off hook in Originate mode and dial the number that follows. Optional parameters: P Pulse dial (Default). T Touch-Tone dial. , (Comma) Pause for 2 seconds. ; Return to Command mode after dialing. " Dial the letters that follow. ! Transfer call (flash switch-hook). W Wait for second dial tone (with X3 or higher). @ Wait for an answer (with X3 or higher). R Reverse frequencies. DS Dial the phone number stored in NVRAM. D$ Help Dial command summary request.

Q1 Result codes suppressed (quiet). Q2 Result codes suppressed in Answer mode. Sr=n Set S-Register value: r is any S- Register; n must be a decimal number between 0 and 255, unless otherwise specified in Appendix B. For bit-mapped registers, n = the total values of the enabled bits. Sr? Query contents of register r. S$ Help S-Register summary request. T Touch-Tone Dial.
