	RTTY, the first digital mode, is a keyboard-to-keyboard mode. RTTY was developed before computers were widely available; originally, special electric typewriters were connected to hardware radio modems. However, the use of these systems is now rare; the majority of RTTY operators use computer software that modulates and demodulates the tones using the computer sound card. PSK31 operators virtually always use a computer for modulation and demodulation. PSK31 has several advantages over RTTY, including improved reliability and support for lowercase letters. JS8 is even more reliable than PSK31, although it is significantly slower and, like RTTY, does not support lowercase letters. JS8 uses much of the same technology as FT8.
