Article-I.D.: azure.1408 Posted: Tue Nov 2 10:46:23 1982 Received: Wed Nov 3 05:20:51 1982 The documentation for the tty driver clearly states that no processing is done in RAW mode. In real life, the driver echoes certain non-printing characters such as ACK. It is necessary to explicitly disable ECHO when in RAW to prevent this from happening. It is obvious from the driver source listing that this is intentional. Can anyone tell me why? Jon Steinhart, Tektronix, Inc.
