A question for all you GS experts:
	
	I know how to read the 16-bit status register (or at least I'm reading 
16 bits)  with the GS/OS DStatusGS call, but I don't know what any of the bits
mean, except that an AND mask of $0020 checks if the receive register is full.
Now, what I need to know is WHAT DO THE OTHER BITS REPRESENT?? Specifically,
I need to know which bits represent ready to transmit, and carrier detect.
I would like to know what all of them mean, though....

	If someone could send me this info, I would be eternally grateful!

thanks in advance,
	-J
