+ER: ALT
V.42 alternative protocol is in use.
+ES=<orig_rqst>,<orig_fbk>,<ans_fbk>±Error Control Selection
Use this command to select the error correction mode. If the modem is
operated in V.80 mode (synchronous buffered mode), and
+ES=,,8,
the

+ES
command is overwritten by the setting on a
\N
command.
+ES Combinations:
+ES=1,0,1
Buffered mode.
+ES=0,1,0
Direct mode.
+ES=4,4,6
MNP or disconnect mode.
+ES=3,3,5
LAPM or disconnect mode.
+ES=4,0,6
MNP or buffered mode.
+ES=3,0,2
LAPM, MNP, or buffered mode (default).
+ES=2,0,2
LAPM or buffered mode.
+ES=3,2,4
LAPM, MNP, or disconnect mode.
+ES=,,8
V.42 sync buffer mode (V.80 enabled).
+ES=6,,8
V.42 sync buffer mode (V.80 enabled).
+ESR=<value>±Selective Repeat
Use this command to enable or disable the selective reject mode.
