BOOL CEnumSerial::Win9xListPorts(CArray<SSerInfo,SSerInfo&> &asi)
/* Information on communications ports is stored in various places in the registry under
* the HKEY_LOCAL_MACHINE\ENUM key. The structure of the HKLM\ENUM key, where information
* on all hw devices present on the system is stored, is as follows
*
* HKLM\ENUM
* |-LEVEL1
* |-LEVEL2
* |-LEVEL3
* · CLASS
*
* LEVEL1 keys indicate the type of technology (vg., "PCI", "BIOS", "SCSI"). LEVEL2
* keys refer to the type of device. So, for instance, "*PNP0501" is for 16550A UARTs.
* LEVEL3 keys enumerate actual devices installed on the system. The value "CLASS",
* present in all LEVEL3 keys, informs about the type of driver. For our purposes, we must
* pay attention to the Class "Ports", that includes serial as well as parallel ports.
* In these cases, another two values, "PORTNAME" and "FRIENDLYNAME" are expected.
* An example follows. Typically, COM1 is recognized as a PnP device by the system BIOS
* and as such placed on the registry like this:
*
* HKLM\ENUM
* |-BIOS
* |-*PNP0501
* |-0D (or any other value, this is not important for us)
* · CLASS= "Ports"
* · PORTNAME= "COM1"
* · FRIENDLYNAME= "Communications Port (COM1)"
*
* Win9xListPorts() scans all LEVEL3 keys under HKLM\ENUM searching for the Class
* for ports, and when this is found determines, by means of "PORTNAME", whether the
* device is a serial port or not.
