/The US Access Board has the following definition in its latest proposal 
for Accessible procurement, Section 508. E.103.4
TTY./  Equipment that enables interactive text based communications 
through the transmission of frequency-shift-keying audio tones across 
the public switched telephone network.  TTY includes devices for real 
time text communications and voice and text intermixed communications.  
Examples of intermixed communications are voice carry over and hearing 
carry over.  One example of a TTY is a computer with TTY emulating 
software and modem.

It is a bit special that we have a North American and an international term.

It looks strange to devote so much space and effort to get the US term 
properly explained. Shall we just delete TTY, and only say Text telephone ?
