An incoming message does not make sense.
If you have a handset in the acoustic cups, press it firmly into the

Because Baudot code does not support special characters, it does not
recognize some of the “shift” characters on the top row of a TTY
(example: @#$%^&*_<>). To type these characters (such as
in an email address) make sure your call is connected in Turbo Code
(see About Turbo Code on page 23).
