5.7.14 &Mn - Asynchronous/Synchronous Mode
Select the DTR operating mode.
0 Selects normal asynchronous operation (default). (See &Qn)
5.7.15 &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.
0, 6 Normal asynchronous operation with no error correction (unacknowledged mode)
5 Asynchronous operation with error correction (acknowledged mode) (default)
