Voice Mode Shielded Codes - Multitech MultiModem SocketModem MT9234 Series At Commands Reference Manual

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. Table 3
describes voice mode shielded codes. The number in the first column is the ASCII equivalent (in hex).
