C-Kermit and K95 both allow 127 and 255 to be unprefixed IF and
ONLY IFF the characters are not known to be dangerous. For instance
255 cannot be sent unprefixed on a telnet connection. 127 with some
forms of parity would be 255 so that is treated the same.
The MS-DOS Kermit rules are left over from a more conservative day.
