The net mask of 255.255.252.0 provides 10 bits of locally accessible IP
addresses, instead of only 8 bits like the normal netmask (255.255.255.0),
so the opposite is true.  Perhaps you were thinking the netmask was
255.255.255.252, but that was not the case here.

That's one way to fix it, but since the netmask is usually assigned to the
PC automatically as part of the DHCP mechanism, just correcting the
broadcast address in each Win-Test instance, and in wtDxTelnet, was a much
easier fix..
