Configuration Commands
Rev 3.0B Feb.08 126
• n=0 : Use hardware DTR. (default).
• n=1 : Ignore DTR.
• n=3 : Ignore DTR and assert DSR. This value is deprecated,
and it is recommended 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.
Vn
Command Response Mode.
• n=0 : Terse (numeric) command responses
• n=1 : Verbose command responses (Default).
Xn
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.
&Cn
Set DCD mode.
• n=0 : Always assert DCD.
• n=1 : Assert DCD when in a data mode (UDP, TCP, PPP, or
SLIP) (Default).
• n=2 : Assert DCD when the modem has network coverage.
&Dn
Set DTR mode.
• n=0 : Ignore DTR, same effect as HW DTR always asserted
(same as S211=1).
• n=2 : Use hardware DTR (same as S211=0).
&Sn
Set DSR mode.
• n=0 : Always assert DSR (Default).
• n=1 : Assert DSR when in a data mode (UDP, TCP, PPP, or
SLIP) (Default).
• n=2 : Assert DSR when the modem has network coverage.
Tip: S211 can also be used to request that DSR is always asserted. If
S211 is set to 3 and &S is changed to a non-zero value, S211 will be
changed to 1.
