DMC: Fixed auto configure when DMC/DMR devices are enabled
Added optional alternate radix output display for device address and vector values.  -H and -O switches select hex or octal output in addition to the default radix displayed by the normal simulator.
TMXR: Fix clearing of break input buffer now that input buffers are dynamically allocated

Changed Modem bit logic to have CTS reflect RTS as expected by devices which may expect this.
