well reading the driver description we only support win7+  
“Below are the available Windows 7/ Windows 8 /Windows 10 Driver Package for MC Series Modules.”

You can still try the QMI driver:  
[https://source.sierrawireless.com/resources/airprime/software/airprime-em\_mc-series-windows-drivers-qmi-build-latest-release/](https://source.sierrawireless.com/resources/airprime/software/airprime-em_mc-series-windows-drivers-qmi-build-latest-release/)

So you are running QXDM on the XP?  
QXDM also supports connection through a socket.

for example:  
on linux I’m running UART to socket app (remserial) this is the client and QXDM / QPST is the server  
./remseriali386 -r “$WindowsIP” -p “$Port” -s “115200 raw” “$ModemDM”

ModemDM="/dev/ttyUSB0"
