Permanent memory, not user-programmable. The Business Modem's
factory settings are stored in ROM.
A feature that allows a remotely-located user to view the Business
Modem's configuration screens and change the Business Modem's
configuration. Password protection is available.
A test that checks the phone link and a remote modem's transmitter
and receiver. Data entered from the keyboard is transmitted from the
initiating modem, received by the remote modem's receiver, looped
through its transmitter, and returned to the local screen for verification.
A copy of the data received by the remote system, returned to the
sending system and displayed on the screen. Remote echoing is a
function of the remote system.
Another way of saying "status message." The Business Modem sends
result codes to your terminal, for example, to indicate the status of a
connection.
The Universal Standard Order Code (USOC) standard for wiring a
single-line, two-wire phone network interface, passing tip and ring
signals, typically, from the public switched network.
See Read-Only Memory.
A simple protocol that permits sending IP data over a serial line. SLIP is
being superseded by the Point-to-Point Protocol (PPP).
A computer port that enables the transmission of data characters one
bit at a time, using a single electrical path. Also known as a
communications port, or COM port. On PC-compatible machines, this is
a port for asynchronous, serial data transmission and, in the case of
modems, for data reception. Data is transmitted one bit at a time
(serially) to devices such as a modem, a serial mouse, or a serial printer.
The transfer of data characters one bit at a time, sequentially, using a
single electrical path. See Parallel Transmission.
A form of flow control that uses XON and XOFF characters to start and
stop the flow of data.
The signaling bit attached to the beginning of each character before
characters are transmitted during Asynchronous Transmission.
