pager
beeper
bleeper
1. <hardware, communications> (Or "beeper", "bleeper" (UK?))
A small wireless receiver that, when triggered (generally via
phone), will beep or vibrate (un)pleasantly. The wearer will
have been trained to respond to this signal by looking at a
small screen on the device for an unimportant message.
In recent years, pagers have grown more complex, allowing for
long {alphanumeric} messages to be received and scrolled
though (as opposed to earlier models, which supported only
short numeric messages); at the same time as pager functions
are integrated into some {PDAs}. If this trend continues, the
distinction between {PDAs} and high-end {pagers} will
disappear.
{Short Message Service} allows a mobile phone to display a
message, just like an alphanumeric pager.
2. <tool> A program for viewing a {text file} a screenful at a
time via a text {terminal}, as opposed to scrolling through it
in a {GUI} window, or {cat}ting it all at once to the
terminal.
The best known pagers are {more}, {less}, pg and list.com.
