Sierra Wireless EV-DO manual Rev 3.0B Feb.08 126

Configuration Commands

•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.
