MVP144i - Remove \N3\C1\V1 from default Quarterdeck Internet Suite init string
The MVP144i and MVP144XF are RPI (software error correction and data cormpression) modems. They work rather well if the comm application's DTE is set to 57,600 and +H3 is added to the initialization string while the WinRPI drivers are loaded.

--------Win 95 installation instructions
!!!DO NOT INSTALL THE MODEM YET!!!
--Disable a COM port in the system setup or I/O controller card (prefferably COM 2).
--Install a COM port in Windows by opening My Computer | Control Panel | Add New Hardware. Do not let windows detect the hardware. Choose Ports as the hardware type. --Install the modem.

NOTE: The MVPxxxI2 series uses a program called PnPset that loads upon bootup in the autoexec.bat file. By default, the command line for the PnP drivers will load on the last line of the autoexec.bat. If you have the line "win" in your autoexec.bat, you need to move the pnpset... command line before the win command line or the PnP drivers will not load until after you exit Windows.

Follow the setup instructions given above, except choose an AT compatible 28.8KBps as the modem type in the Quarterdeck Internet Suite set up.

AT&F&C1&D2&K3S7=60 usually works as an acceptable init string for the modems listed above.
Remember to add +H3 for the RPI modems (after the WinRPI drivers have been loaded).
