The specific acceptation of the appellation impaired terminal can alter depending on the ambience in which it is used.
In the ambience of acceptable computer terminals that acquaint over a consecutive RS-232 connection, impaired terminals are those that can adapt a bound amount of ascendancy codes (CR, LF, etc.) but do not accept the adeptness to action appropriate escape sequences that accomplish functions such as allowance a line, allowance the screen, or authoritative cursor position. In this ambience impaired terminals are sometimes dubbed bottle Teletypes, for they about accept the aforementioned bound functionality as does a automated Teletype. This blazon of impaired terminal is still accurate on avant-garde Unix-like systems by ambience the ambiance capricious TERM to dumb. Smart or able terminals are those that aswell accept the adeptness to action escape sequences, in accurate the VT52, VT100 or ANSI escape sequences.
In the broader ambience that includes all forms of keyboard/screen computer advice devices, including claimed computers, diskless workstations, arrangement computers, attenuate clients, and X terminals, the appellation impaired terminal is sometimes acclimated to accredit to any blazon of acceptable computer terminal that communicates serially over a RS-232 affiliation that does not locally action abstracts or assassinate user programs.citation needed
The appellation impaired terminal sometimes aswell refers to accessible computer terminals that are bound to connected text-only capabilities, or to terminals that address anniversary appearance as it is typed rather than cat-and-mouse until it is polled by a host computer.
