Initiating conditions
In order for the DAC to respond to user commands/entries, the following
conditions must be met:
•
The DAC must be active (power ON), and successfully receive the
downloaded parameters from the system.
•
The user equipment must be active, and, if in RS-232-C mode, must
assert these control lines
— DCE mode: DTR (unless Forced DTR has been software selected)
— DTE mode: RI has cycled the appropriate number of times
Echo
During call setup (dialogue phase), all user input is echoed back to the
user equipment. Once the call is established, the DAC is transparent to
data communication. To get echoed characters after a call is established,
the far end must provide the echo.
Note: When RS-232-C modes 12-15 (Host modes) are selected, there
is no echo during dialogue phase.
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 (:).
