WinSpool.Drv SetPort function fails

2010-02-09T16:10:43Z

When calling SetPort function implemented in WinSpool.Drv within .NET, you may get following error: 0x0000007C - The system call level is not correct. After intensive digging in internet I didn’t find anything related to this error. The problem is that obviously nobody has ever called it within .NET. This is reasonable, because this function is designed to be called within one port monitor , and port monitor is always written in C++ as user mode driver. Till now. The error above has no logical meaning...(read more)
