Flow Control
XON/XOFF flow control is used by the modem to match the PC-to-modem data rate to the line-signaling
rate, as well as to the requirements of analog conversion of the voice signals and voice data.
In-band, uni-directional XON/XOFF flow control is mandatory. RTS/CTS (V.24 circuits 106 and 133) flow
control is optional per the IS-101 standard.
Voice Mode Result Codes
In Voice mode, the modem can detect and report DTMF, detect call progress tone and cadence events,
evaluate voice quality, and can monitor Telco-related activities. Events can be reported as a single
character (Simple or "Terse" reporting), a full-text message (Message or "Verbose" reporting), or as a
repeating pattern (Pattern reporting).
