Table 11. Basic AT Command Set (Command Defaults in Bold) (Continued)
S-register operation (see Table 20 on page 40).
List contents of all S registers.
Display contents of S-register n.
Set S-register n to value x (where n and x are decimal values).
Result code type (see Table 16 on page 33).
Numeric result codes.
Verbal result codes
Call Progress Monitor (CPM)—This command controls which CPM signals are monitored and
reported to the host from the Si2456/33/14. (See Table 16 on page 33.)
Basic results; disable CPM—Blind dial (does not wait for dial tone). CONNECT message does not
include speed.
Extended results; disable CPM—Blind dial. CONNECT message includes speed.
Extended results and detect dial tone only—Add dial tone detection to X1 mode. Does not blind dial.
Extended results and detect busy only—Add busy tone detection to X1 mode.
Extended results, full CPM—Full CPM enabled, CONNECT message includes speed.
Extended results—Full CPM enabled including ringback detection. Adds ringback detection to X4
mode.
Long space disconnect—Modem hangs up after 1.5 seconds or more of continuous space while on-
line.
Disable.
Enable.
Hard Reset—This command is functionally equivalent to pulsing the RESET pin low. (See t
Table 6 on page 8.)
Interrupt Read—This command causes the ISOmodem to report the lower 8 bits of the interrupt reg-
ister I/O Control 0 (U70). The CID, OCD, PPD, and RI bits also are cleared, and the INT pin (INT bit
in parallel mode) is deactivated on this read.
Program RAM Write—This command is used to upload firmware supplied by Silicon Labs to the
Si2456/33/14. The format for this command is AT:Paaaa,xxxx,yyyy,.... where aaaa is the first address
in hexadecimal and xxxx,yyyy,.... is data in hexadecimal. Only one :P command is allowed per AT
command line. No other commands can be concatenated in the :P command line. This command is
only for use with special files provided by Silicon Laboratories. Do not attempt to use this command
for any other purpose.
User-Access Register Read—This command allows the user to read from the user-access registers.
(See pages 42–62.) The format is “AT:Raa”, where
aa = user-access address in hexadecimal.
The “AT:R” command causes all the U- registers to be displayed.
User-Access Register Write—This command allows the user to write to the 16-bit user-access regis-
ters. (See page 42.) The format is “AT:Uaa,xxxx,yyyy,zzzz,...” where
aa = user-access address in hexadecimal.
xxxx = data in hexadecimal to be written to location aa.
yyyy = data in hexadecimal to be written to location (aa + 1).
zzzz = data in hexadecimal to be written to location (aa + 2).
etc.
