AOL has unveiled instant messaging software that will function in a way familiar to users of TTY devices. It lets users see each letter IM users type in real time, rather than waiting for a friend or buddy to press the Enter or Return key. The beta version of AIM 6.8 was developed with help from Gallaudet and the Trace Research and Development Center at the University of Wisconsin. To try the new feature, select Real-Time IM inside an instant messaging window or you can select a buddy from the Buddy List and press Control-R.
