Help with MC7455 in WinPE

I am trying to swap modes in WinPe and send a few AT commands to the modem.

Is it possible to swap modes in Window PE?
Is it possible to send AT command to it in WinPE?

Do you have drivers for the serial port installed in Winpe?

I did an extract from the live drivers from Windows 10 using powershell and then imported them to the WInPE so yes I believe I have them installed.
