Initiating conditions
The DAC responds to commands only when the following initial requirements
are met:
• the DAC is active
• the DAC has successfully received the downloaded parameters
• the user equipment is active, and, if operating in RS-232-C mode
— the DCE mode is DTR (unless Forced DTR has been software
selected)
— the DTE mode, and RI has cycled the appropriate number of times
and DCD is asserted on by the modem
Note: In Gateway mode, DCD must be asserted on. In modem mode,
only RI must be on. The DAC asserts DTR to the modem, and awaits
DCD from the modem.
Input requirements
All input must be in the same case (upper or lower).
The Hayes repeat command, A/, is used to immediately execute the last
command entered. The terminator character need not be entered. A
complete discussion of the Repeat command can be found later in this
document.
Where a Dial Number is expected, you may enter the characters 0-9, #, and
comma (,). The characters @, P, R, T, and W are accepted, but ignored.
