V.32bis
A standard for modems operating full-duplex with asynchronous or synchronous data over dial
networks (PSTN) or leased lines at 14,400, 12,000, 9600, 7200, or 4800 bps.
V.32terbo
A proprietary standard for modems operating full-duplex with asynchronous or synchronous data
over dial networks (PSTN) or leased lines at 19,200 or 16,800 bps. The terbo is a pun on turbo
and ter; the next iteration of the V.32 recommendation, had one been finalized, would have been
V.32ter.
V.34
A standard for modems operating full-duplex with asynchronous or synchronous data over dial
networks (PSTN) or two-wire leased lines at 28,800, 26,400, 24,000, 21,600, 19,200, 16,800,
14,400, 12,000, 9600, 7200, 4800, or 2400 bps.
V.42
CCITT standard for error control protocol.
V.42bis
CCITT standard for data compression.
V.54
CCITT standard for local and remote diagnostic loopback tests.
VF
Voice Frequency. The part of the audio frequency range used to transmit voice sound (usually
300 Hz to 3400 Hz). This band is used by the modem for its modulated signal.
XOFF
A character that tells the DTE or modem to stop transmitting data.
XON
A character that tells the DTE or modem to start or resume transmitting data.
