n=0 : No forwarding character.
Used in UDP or TCP PAD mode.
For applications or situations where hardware control of
the DTR signal is not possible, the
modem can be configured to ignore DTR. When Ignore DTR is enabled, the modem operates
as if the DTR signal is always asserted.
n=0 : Use hardware DTR. (default).
n=1 : Ignore DTR.
n=3 :
Ignore DTR and assert DSR. This value is deprecated, and it is rec
ommended to use &S to control
the DSR instead. When this value is set to 3, &S will automatically be set to 0. See also: &D and &S.
Command Response Mode.
n=0 : Terse (numeric) command responses
n=1 : Verbose command responses (Default).
Extended Call Progress Result mode.
n=0 : Turn off extended result codes (Default).
n=1 : Turn on result codes. This adds the text
19200 to the CONNECT response.

In Wireless Ace, this command is performed with the Reset option on the toolbar.

n=1 : Assert DCD when in a data mode (UDP, TCP, PPP, or SLIP) (Default).
n=2 : Assert DCD wh
en the modem has network coverage.
