For proper enumeration of Sealevel multiport serial adapters, the following components must be included in the Microsoft Windows XP Embedded OS image build:
“Class Installer – Multifunction adapters [Version 5.1.2600.2180, R2890]”
“Class Installer – Multi-port serial adapters [Version 5.1.2600.2180, R2890]”
Ensure that mf.sys is included in the Windows/Systems32/Driver directory. Also make sure that the current SeaCOM serial driver is installed prior to installing the serial adapter hardware.
Microsoft Windows requires these drivers and components to be installed so that Sealevel multiport serial devices will install properly and enumerate.
