Re: Problem with CyberKnex Programmer program and direct LPT1 port access

[Juan Lang]

Hey Terry, update:  according to my registry on WinXP, "Ports" should
return the GUID {4D36E978-E325-11CE-BFC1-08002BE10318}.  This is also
known as GUID_DEVINTERFACE_SERENUM_BUS_ENUMERATOR.  Right now that GUID
used with SetupDiGetClassDevs returns serial ports, and it should return
both serial ports and parallel ports.

Hope that helps,
--Juan
