There are some etiquette rules that users of TDDs must be aware of. For example, because of the inability to detect when a person has finished speaking, the term "Go Ahead" (GA) is used. Commonly used abbreviations: BRB - Be Right Back; CA - Communications assistant (another term for a relay operator); CU - See You (be seeing you). GA - Go Ahead; SK - Stop Keying; SKSK - Now hanging up; Q, QQ, QM - Question Mark (?); PLS - Please; RO - Relay Operator; OIC - Oh, I See; OPR - Operator; NBR - Number; TMW - Tomorrow; THX - Thanks; WRU - Who are You? (or Where are You?); XXXX - Xs are often used to indicate a typing error instead of backspacing.
