User's Manual

Enables or disables automatic adjustment of the transmit power level during link negotiation for reliable
links to accommodate the signaling requirements of cellular telephone equipment. The parameter value, if
valid, is written to S40 bit 2. Note that the @Mn command sets the initial transmit level.
)M0 Disables power level adjustment during MNP 10 link negotiation. (default)
)M1 Enables power level adjustment during MNP 10 link negotiation.
Result Codes:
OK n = 0 or 1.
ERROROtherwise.
AT-Commands
*Hn Link Negotiation Speed
This command controls the connection speed for link negotiations before upshift occurs between two MNP
Class 10 modems. The parameter value, if valid, is written to S28 bits 6 and 7.
*H0 Link negotiation occurs at the highest supported speed. (default)
*H1 Link negotiation occurs at 1200 bps.
*H2 Link negotiation occurs at 4800 bps.
Result Codes:
OK n = 0 to 2.
ERROR Otherwise.
-Kn MNP Extended Services
Enables or disables conversion of a V.42 LAPM connection to an MNP 10 connection. The parameter
value, if valid, is written to S40 bit 0, 1.
-K0 Disables V.42 LAPM to MNP 10 conversion.
-K1 Enables V.42 LAPM to MNP 10 conversion. (default)
-K2 Enables V.42 LAPM to MNP 10 conversion; inhibits MNP Extended Services initiation during
V.42 LAPM answer mode detection phase.
Result Codes:
OK n = 0 or 1.
ERROR Otherwise.
-Qn Enable Fallback to V.22 bis/V.22
Enables or disables fallback from MNP 10 to V.22 bis/V.22. The parameter value, if valid, is written to S41
bit 7.
-Q0 Disables fallback to 2400 bps (V.22bis) and 1200 bps (V.22). Fallback is enabled only to 4800
bps.
