Chapter 3 – Voice Commands

Unformatted Form Reporting – Caller ID

The MultiModem does not display the Caller ID information if it detects a checksum error in the caller ID packet (either SDM or MDM) while in presentation mode. If the MultiModem receives multiple copies of the Caller ID packets, the MultiModem presents all of the packets to the computer. The MultiModem presents all data items and packet control information found in the SDM and MDM packets, except the leading Us (line seizure information) from the presentation. The checksum is included in the presentation. The entire Caller ID packet is presented in ASCII hex as printable numbers. The characters in the ASCII hex message are in the bit order presented to the MultiModem. The MultiModem does not insert spaces, <cr>, or <lf> ASCII codes for formatting between the characters of the packet.

The MultiModem does not check the checksum, and it is the computer’s job to check message validity. Note that this means that the MultiModem presents the Caller ID information even if the MultiModem detects a check sum error in the Caller ID packet (SDM or MDM) in the presentation mode.

The MultiModem presents all of the information in the packet in ASCII hex as printable characters. The MultiModem includes all Message Type Octets, Message Length Octets, Data Octets, and Checksum Octets for the presentation mode.

Voice Mode Shielded Codes

These codes can be sent in either Command mode or Data mode. The DCE may return the event detection reports after the OK result code from the +FCLASS command. One or more simple event detection reports may be embedded within the data portion of a complex event detection report. The Table below describes voice mode shielded codes. The number in the first column is the ASCII equivalent (in hex). The number in the second column refers to the numbering scheme used below.
