36 56K Message Modem
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 dialling 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 analogue transmission from
one point to another. Although not technically accurate, baud rate is
commonly used to mean bit rate.
binary digit (bit)
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 33,600.
bits per second (bps)
The bits (binary digits) per second rate. Thousands of bits per second
are expressed as kilobits per second or Kbps.
buffer
A memory area set aside to be used as temporary storage during input
and output operations. An example is the modem's command buffer.
