Baud rate detection
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 are placed in keyboard dialing mode.
Parity detection
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.
Note: The parity determined here overrides the parity downloaded from
the system. Also, the T (t) must be entered in the same case as the A
(a). If you entered uppercase A for the Baud Rate, you must enter upper
case T for the parity.
