Never heard about it.
if you look through the Windows drivers and some of the .inf files, you find the QMI and most likely it means Qualcomm Management Interface. And there is also QMUX which is kind of a multiplexer similar to what Phonet does for the Nokia protocol. The QMI is similar to ISI from Nokia. Look through the MSM stuff from the Android kernel tree since they are also using some of these terms. And I guess all MSM modems are similar one way or the other.
