  Telecommunications devices for the deaf - Wikipedia, the free encyclopedia
A telecommunications device for the deaf (TDD) is an electronic device used for telephone communications by deaf persons and those with other hearing difficulties.
The typical TDD or textphone is a device about the size of a small laptop computer with a QWERTY keyboard and small screen that uses light-emitting diodes or an LCD screen to display typed text electronically.

 Telecommunications Device for the Deaf - Computing Reference - eLook.org
The acronym TDD is sometimes expanded as "Telecommunication Display Device" but is generally considered to be derived from "Telecommunications Device for the Deaf", although there is some disagreement on this.
The standard most used by TDDs is reportedly a survivor of Baudot code implemented asynchronously at 45.5 or 50 baud, 1 start bit, 5 data bits, and 1.5 stop bits.
A typical TDD is a device about the size of a small laptop computer (resembling, in fact, a circa 1983 Radio Shack Model 100 computer) with a QWERTY keyboard, and small screen (often one line high, often made of an array of LEDs).

The telephone or phone (Greek: tele = far away and phone = voice) is a telecommunications device which is used to transmit and receive sound (most commonly voice and speech) across distance.
Such devices tend to be bulkier than cell-based mobile phones, as they require a large antenna or dish for communicating with the satellite, but do not require ground based transmitters, making them useful for communicating from remote areas and disaster zones.
There are phones that work as a cordless phone when near their corresponding base station (and sometimes other base stations) and work as a wireless phone when in other locations but for a variety of reasons did not become popular.

That should be enough to, in the meantime, if I find someone interested that has more coding capability than a turnip (which is about my level) could code something up to work as a standalone piece of software.
FWIW, for US anyway, traditional TDD's use 45.45 baud, 5 data bits, no parity, one and a half stop bits (weird, I know), 1400Hz and 1800Hz FSK, I'm assuming, but haven't found any information to support for sure, that the 1800Hz is a 1, and 1400Hz is a 0 in the transmission.
Most of this information, I would assume, is included in the V.18 recommendation, and probably more as the V.18 recommendation is inclusive of many of the international standards as well (50 baud rather than 45.45 baud is common from what I understand).
