SYMPTOMS
Some models of the IBM MWave 28800 modems do not work with Remote Access Service (RAS) and other communications software. However, the same modems sometimes appear to function properly with Windows Terminal or other communications software.



CAUSE
The IBM MWave 28800 modems are not on the Windows NT 3.51 Hardware Compatibility List (HCL). Windows NT detects these modems as generic 28800 modems, and may drop connections intermittently.



RESOLUTION
To resolve this problem, update the existing Modem.inf file in the %Systemroot%\System32\Ras directory by appending the following information:



[Mwave 28800]

=M1

=M0

=ATDT

=ATX3D

=M1

=M0

=&K3

=&K0

=%C1"H3

=%C0"H0

=\\N7

=\\N0

CALLBACKTIME=10

DEFAULTOFF=compression

MAXCARRIERBPS=28800

MAXCONNECTBPS=57600

DETECT_STRING=ATI3<cr>

DETECT_RESPONSE=IBM Mwave Modem v3.0

COMMAND_INIT=AT&F&C1&D2 V1 S0=0 S2=128 S7=55<cr>

COMMAND_INIT=AT   <cr>

COMMAND_DIAL= <cr>

COMMAND_LISTEN=ATS0=1<cr>

IBM also suggests that you set the PORT flow control to hardware and click to select FIFO under advanced settings.
