Figure 8-1: AceManager : UDP - MD
If the serial port of the PinPoint X is in any mode other than AT
or PassThru, the AT command mode can be re‐entered by:
• Deactivating DTR (if &D2 or Ignore DTR, S211, is not set).
• Issuing the +++ escape sequence (if Disable AT Escape,
DAE, is not set).
• Resetting or Power cycling the modem.
Note: DTR needs to be asserted (S211=1 or &D0) by the host before
PPP Mode, SLIP Mode, UDP PAD Mode, or TCP PAD Mode can be
entered.
AT Mode
Using a terminal connection, AT commands are used to
configure the modem, command it to do something, or query a
setting. For a full listing of the AT commands, refer to the
appendix. AceManager is a graphical user interface for most
AT Commands.
• AT commands must always be terminated by <CR> (ASCII
character 0x0D), a carriage return (pressing enter on the
keyboard). Some may also include a new line or line feed
<LF>.
• If E=1 (Echo On), the AT command (including the termi‐
nating <carriage return) will be displayed (output) before
any responses.
• Two settings affect the format of AT command output: V
(Verbose) and Q (Quiet).
• If Q=1 (Quiet On), no result codes are output whatsoever,
so there is no response generated by a (non query)
command.
• If Q=0 (Quiet Off), result codes are output. The format of
this output is then affected by the Verbose setting.
