K40 RTTY Module Guide
... There are three K40 outputs used for transmitting, PTT, KEY, and FO. The K40 PTT output is used to key your transceiver and switches to ground when active. This usually goes to the key input but check your transceiver’s manual to be sure. The K40 KEY output is used to frequency shift key your transc ...

Radioteletype
Radioteletype (RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. These machines were later superseded by personal computers (PCs) running software to emulate teleprinters. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. The US Navy Department successfully tested printing telegraphy between an airplane and ground radio station in 1922. Later that year, the Radio Corporation of America successfully tested printing telegraphy via their Chatham, Massachusetts, radio station to the R.M.S. Majestic. Commercial RTTY systems were in active service between San Francisco and Honolulu as early as April 1932 and between San Francisco and New York City by 1934. The US military used radioteletype in the 1930s and expanded this usage during World War II. From the 1980s, teleprinters were replaced by computers running teleprinter emulation software.The term radioteletype is used to describe both the original radioteletype system, sometimes described as ""Baudot"", as well as the entire family of systems connecting two or more teleprinters or PCs using software to emulate teleprinters, over radio, regardless of alphabet, link system or modulation.In some applications, notably military and government, radioteletype is known by the acronym RATT (Radio Automatic Teletype).
