Every command line begins with Baud rate detection. This phase allows the
DAC to determine the user equipment baud rate. During this phase, the DAC
accepts only the ASCII "A," or "a" characters. Once a valid autobaud
character is detected, the DAC echoes the parity bit character at the baud rate
detected.
Note: If Hayes dialing is desired, you must enter the character "A" or
"a" BEFORE the <CR>. If Carriage Return (<CR>) is entered before this
Hayes dialing command, you will be placed in keyboard dialing mode.
Once the baud rate has been determined, the DAC accepts only the ASCII
characters "T," "t," or "/." If the Repeat character "/" is entered, the previous
command is executed. If "T," or "t" is entered, the DAC uses its parity and
the parity of the preceding A (a) to determine the user's parity. This parity is
used on the following messages and prompts associated with the command
lines.
