Is Real-Time Text compatible with TTY?
Yes, you’ll be able to converse with RTT and TTY users. But, TTY has more functional limitations than RTT. When a RTT user is communicating with a TTY user, both parties will be constrained by the limitations of the TTY device. For example, TTYs are limited to 50 characters while RTT has no character limits. TTY etiquettes like Go Ahead “GA” or Stop Keying “SK” can be used for turn taking.
