Prompts

Call processing prompts are in upper case letters only. Other prompts consist of both upper and lower case characters, and the dialogue session depicts the actual upper/lower case letters used.

All prompts are preceded by the Carriage Return and Line Feed ASCII characters (<CR>, <LF>).

Prompts requesting user input are terminated with the ASCII colon (:).

Prompts requiring a Yes or No answer are terminated by a question mark (?), followed by a list of allowable responses. The default response, if allowed, is bracketed.

Call abort

In addition to the methods mentioned above, which are common to both Hayes and keyboard modes, keyboard dialing supports the following method to abort a call during the dialogue phase.

Sending the Control Z character (simultaneously pressing the control and Z keys) sends a message to the DAC to immediately abandon the data call setup.

Autobaud

All user dialogue must begin with Autobaud detection. This allows the DAC to determine the user equipment baud rate. During this phase, only <CR> will be recognized by the DAC. All other entries are ignored, and no entries are echoed. Once a valid <CR> is detected, the DAC responds with the New Menu prompt at the baud rate detected. If a fixed rate has been determined by the downloaded parameters, the DAC will look for that rate. If the rates agree, the dialogue phase begins. If not, the following prompt is sent to the user:

Baud Rate xxxx expected

After receiving a number of invalid responses, the DAC reverts to autobaud detection, since the terminal data speed may have changed.
