I've been trying to completely disable V92 on my USR modem (5630-04). Disabling call waiting, pcm upstream (i know, not supported by usr) and quick connect, doesn't help - I keep getting V92 connects with my ISP. I want to set up a connection without V92. The AT +MS command is not supported, so... Does anyone know to do this?
Kind regards,

+PIG=1 Disables PCM Upstream support.
+PMH=1 Disables Modem-on-hold.
+PQC=3 Disables the Quick Connect sequence

Disabling the quick connect sequence shouldn't have any effect during an ongoing session. Disabling MOH may prevent the modem from dropping the connection in response to an incoming call, assuming you have call waiting. If it is a line related problem, then disabling upstream PCm would be the most likley to have a beneficial effect.

In general, the best init string for a USR modem is AT&F1 - factory defaults with hardware flow control. If the ISP's equipment gets confused with an attempted v.92 connect, then disable v.92 with 'S32=130'. The above commands disable certain features of v.92, but I would guess that the S32=130 would be encompassing.

If the line conditions are such that the modem is connecting and trying to maintain a connection too fast for conditions, then using the &Ux and &Nx commands to throttle the speed may be helpful.
