To terminate a test in progress, the escape sequence must be entered first,
except for parameters 7 and 8. If S18 is non-zero, a test will terminate
automatically after the time specified by S18 and display the Ok message.
AT&T0 Terminates test in progress.Clears S16.
AT&T1 Initiates local analog loopback,V.54 Loop 3,Sets S16 bit 0.
If a connection exists when this command is issued, the
modem hangs up.
The CONNECT XXXX message is displayed upon the start
of the test.
AT&T2 Returns ERROR.
AT&T3 Initiates local digital loopback,V.54 loop 2.Sets S16 bit 2.
If no connection exists, ERROR is returned. Sets S16 bit 4
when the test is in progress.
AT&T4 Enables digital loopback acknowledgment for remote
request, i.e., an RDL request from a remote modem is allowed. Sets S23 bit 0.
(Default)
AT&T5 Disables digital loopback acknowledgment for remote
request, i.e., an RDL request from a remote modem is denied. Clears S23 bit 0.
AT&T6 Requests a remote digital loopback(RDL), V.54 Loop2,
without self test.
If no connection exists,ERROR is returned. Sets S16 bit 4
when the test is in progress. The CONNECT XXXX message is displayed upon
the start of the tests.
AT&T7 Requests a remote digital loopback(RDL), V.54 Loop 2,
with self test.(In self test, a test pattern is looped back and checked by the
modem.)
If no connection exists, ERROR is returned. When the test is
terminated either via expiration of S18, or via the &T0 or H command, the
number of detected errors is reported to the DTE. Sets S16 bit 5 when the test is
in progress.
AT&T8 Initiates local analog loopback, V.54 Loop3, with self test.
(In self test, a test pattern is looped back and checked bythe modem.) If a
connection exists, the modem hangs up before the test is initiated. When the test
is terminated either via expiration of S18, or via the &T0 or H command, the
number of detected errors is reported to the DTE. Sets S16 bit 6 when the test is
in progress.This command may not be available in some countries due to PTT
restrictions.
AT&V Display Current Configuration and Stored Profile
Reports the current (active) configuration, the stored(user) profiles,
and the four stored telephone numbers. The stored profiles and telephone
numbers are not displayed if the NVERAM is not installed or is not operational as
detected by the NVRAM test during reset processing.
AT&V1 Display Last Connection Statistics
Displays the last connection statistics in the following format (shown
with typical results):
