'''Teletype''' is the name for the mechanical printing [[terminal]]s for connection to an [[asynchronous serial line]] produced by the Teletype Corporation.

Many different models were produced over the years, but the one most commonly used with computers was the Model 33 - initially produced in the mid-60's, it used the [[ASCII]] code (uppercase only), operated at 10 characters per second, and used a cylindrical typewheel to print.

The Model 33 came in three different varieties:

* ASR (Automatic Send/Receive) - in addition to the keyboards and printer, it included a [[paper tape]] reader/punch on the side
* KSR (Keyboard Send/Receive) - as above, but no paper tape reader/punch
* RO (Receive Only) - only the printer

The ASR-33 (formally the "Model 33 ASR") was widely used on early [[minicomputer]]s, as the paper tape option could be used to load [[binary]] program tapes. Although an [[EIA RS-232 serial line interface|EIA]] interface option was available, most used the [[20mA current loop serial line interface|20mA current loop]] interface.

The later Model 38 added lower case, a number of special symbols, and a two-colour (red/black) printing ribbon.
