Modem Info Wanted

[Tom Palisano]

			I am in the process of building a 300/1200
baud modem with half/full duplex capability.My question is this..
	Is there any standard as to the manner that the signal is 
keyed? I am aware that the 300 baud line is FSK,but is the 1200
necessarily PSK?Also are both asynchronous solely?

				thanks,
				Tom Palisano
