Glossary

S-registers	Registers that contain information affecting modem operation. S-register commands
	must be preceded by the AT prefix.
Sync Dial	A factory preset configuration area containing configuration options most often used in
	synchronous dial networks.

synchronous transmission Data transmission that is synchronized by timing signals. Characters are sent at a fixed

	rate. This type of transmission is more efficient than asynchronous transmission.
tone dialing	One of two dialing methods, in which telephone numbers are sent as tones across the
	telephone lines.
training	A process where two modems try to establish a connection over the VF line.
UL	Underwriter's Laboratories, Inc.
UNIX Dial	A factory preset configuration area containing the configuration options most often used
	in a UNIX dial network.
USOC	Universal Service Ordering Codes.
V.17	A fax communications standard for modems operating half-duplex with synchronous
	data at 14,400 bps.
V.22	A standard for modems operation full-duplex with asynchronous or synchronous data at
	1200 bps over the dial network (PSTN).
V.22bis	A standard for modems operating full-duplex with asynchronous or synchronous data at
	1200 or 2400 bps over the dial network (PSTN).
V.25bis	A dialing protocol that permits direct and stored-number dialing in asynchronous,
	bisynchronous, or HDLC modes.
V.27ter	A fax communications standard for modems operating half-duplex with synchronous
	data at 2400 and 4800 bps.
V.29	A fax communications standard for modems operating half-duplex with synchronous
	data at 7200 and 9600 bps.
V.32	A standard for modems operating full-duplex with asynchronous or synchronous data at
	4800 or 9600 bps on switched (dial) or leased telephone lines.
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 33,600, 31,200, 28,800, 26,400,
	24,000, 21,600, 19,200, 16,800, 14,400, 12,000, 9600, 7200, 4800, or 2400 bps.
V.42	ITU-T standard for error control protocol.
