&M0 Set modem for async
operation
&M1
Enter sync mode after async
dialing
&M2
Sync terminal support. Modem
dials a stored number and
enters sync mode when DTR
off-to-on
&M3
Dial manually while DTR off,
handshake proceeds when DTR
off-to-on
&P0 M/B ratio 39/61(USA)

&Q4
Selects Auto Sync operation.
When used in conjunction with
the Hayes synchronous
interface (HCI)capability in the
DTE. Provides synchronous
communication capability from
an asynchronous terminal
&Q5
The modem will try to
negotiate an error-corrected
link
&Q6
Select asynchronous operation
in normal mode
&R0
Modem turns CTS on when
detects RTS from the local
computer
&R1
Ignore RTS. Modem turns CTS
on when ready to receive
synchronously
&S0 Modem forces DSR always on
&S1
Set DSR to follow RS-232 spec
&T0
Terminates test in progress
&T1
Initiates local analog loopback,
V.34 Loop3, Sets S16 bit0. If
aconnect exists when this
command is issued, the modem
hangsup, The connect xxxx
message is displayed upon the
start of the test.
&T5 Disable digital loopback
acknowledgment for remote
request.
&T8
Initiates local analog loopback,
V.34 Loop3, with selftest.
