Somewhere in the dusty, musty, trivial bits of DOS knowledge that's in the back of my brain I seem to remember that the getc() call under DOS has to be called _twice_ for special characters. The first byte is a flag byte and the second one contains the actual keyboard scan code.

The Term::ReadKey module appears to use getc() or Win32Peek() to get its characters. I'll bet if you get a null (ord==0) and then immediately read for another key you'll get the scan code for the special key. I don't have a MS system handy or I'd test this theory out...

Update:Google does it again. An explanation of getc under ths baroque environment.
