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.

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
(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.

Displays the last connection statistics in the following format (shown
with typical results):
