the call will remain up. If DTR is not restored ON within approximately 10 seconds,
the call will drop to on-hook command mode.
2
If DTR transitions from ON to OFF during either in-call command mode or in-call
data mode, the call will drop to on-hook command mode (default).
3
If DTR transitions from ON to OFF during either in-call command mode or in-call
data mode, the call will drop to on-hook command mode and the A3LA-RS will
reset to AT command profile 0.
A.8.12 &Fn – Restore Factory Settings
Recall factory defaults.
0
Recall factory default 0
A.8.13 &Kn – Flow Control
Select the flow control method between the A3LA-RS and DTE.
0
Disables flow control
3
Enables RTS/CTS flow control (default)
4
Enables XON/XOFF flow control
6
Enables both RTS/CTS and XON/XOFF flow control
A.8.14 &Mn – Asynchronous/Synchronous Mode
Select the DTR operating mode.
0
Selects normal asynchronous operation (default). (See &Qn)
A.8.15 &Qn – Sync/Async Mode
Select asynchronous mode. This is an extension of the &M command and is used to control the
connection modes permitted.
Note:
The register is not updated right after the user requests new values because the
requested values may or may not be what IRLP will use once a data call is established due to
negotiations with the other peer. If the register is updated right away, this may give the user
the impression that those values will be used during the data call, but there is no guarantee
that will be the case. The real values will only be known once a data call is established and the
negotiation phase is done. For that reason, the values are written to the register only after a
call is established and both sides have negotiated parameter values (such as mode of
operation). The value of the register will be reset to default value (5) after the call completed.
