asynchronous transmission

Data transmission in which the length of time between transmitted

characters may vary. Because the time lapses between transmitted

characters are not uniform, the receiving modem must be signaled

as to when the data bits of a character begin and when they end.

The addition of start/stop bits to each character serves this

purpose.

Auto Answer

Sets the modem to pick up the phone line when it detects a certain

number of rings. See S-register S0 in Section D: Technical Quick

Reference.

auto dial

A process where your modem dials a call for you. The dialing

process is initiated by sending an ATDT (dial tone) or ATDP (dial

pulse) command followed by the telephone number to dial. Auto dial

is used to dial voice numbers. See command Dn.

baud rate

A term used to measure the speed of an analog transmission from

one point to another. Although not technically accurate, baud rate is

commonly used to mean bit rate.

binary digit

A 0 or 1, reflecting the use of the binary numbering system. Used

because the computer recognizes either of two states, OFF or ON.

The shortened form of binary digit is bit.

bit rate

Also referred to as transmission rate The number of binary digits,

or bits, transmitted per second (bps). Communications channels

using telephone channel modems are established at set bit rates,

commonly 2400, 4800, 9600, 14,400, 28,800 and higher.

bits per second (bps)

The bits (binary digits) per second rate. Thousands of bits per

second are expressed as kilobits per second or Kbps.
