-#	-DCONSPEED

-#	-DCOMPARM
-#			Set Line Control Register value for data bits, stop

-#			If undefined, defaults to 0x03 = 8N1.
-#	-DCOMPRESERVE
-#			Ignore COMSPEED and COMPARAM and instead preserve
-#			the com port parameters from the previous user

-#			This makes it trivial to keep the serial port

-#			You set the speed in the first user and the
