Hi,
Thank you for the reply. The thing is that Windows XP Embedded 2009 is still supported by microsoft:
“Windows Embedded POSReady 2009. This product for point-of-sale devices reflects the updates available in Windows Embedded Standard 2009. It was originally released in 2009, and extended support will end on April 9, 2019.”
So I hope that there is a driver available for the modem. On the PC there are all kinds of dedicated windows applications which make it difficult to switch to Linux.
Does anybody have a clue?
