You need to evaluate a bitwise AND of the EDF value and the various values
defined in the A2S_INFO specification. I haven't done this in PowerShell, but
a quick Google search for bitwise operations makes me think that you need to
use -band (bitwise AND) instead of -and, like so:
if($EDF -band 0x80)
{
# Server's game port is included
}
if($EDF -band 0x10)
{
# Server's SteamID is included
}
if($EDF -band 0x40)
{
# Spectator port and server name are included
}
if($EDF -band 0x20)
{
# Game tag data is included
}
Again, I haven't actually tried this, but I think the -band may be what you're
looking for.
