It sounds like iswind() might be broken?  Or maybe the
programs aren't even checking?

I've always used "ioctl(0,WIOCGETD,&wd)", see window(7), to
determine if the display was bit mapped.  It will fail and
return non-zero if stdin (fd = 0) is not bitmapped.  I'm
sure it works for terminals connected to serial ports, but
haven't checked it over an ethernet.
