Eary HAL adaptors have been used to connect a conventional mechanical teletypewriter to a commercial shortwave receiver.
Later, fully automatic radioteletype and morse code (CW) decoders were availabe and even affordable for the radio amateur, complete radioteletype terminals provided not only decoding of a RTTY signal but could also used for sending radioteletype messages in the amateur bands.
In the United States, many RTTY decoders sold under the name "Telereader" in Europe carried the HAL label.
