Question about modems

[Jim Brain]

If you look at the values received by an 8N1 connection from a sender 
using the different settings, you get:


	AT
	at
	At
	aT
7E1
	E174
	41D4
	E1D4
	4174
7O1
	61F4
	C154
	6154
	C1F4
7M1
	E1F4
	C1D4
	E1D4
	C1F4
7S1
	6174
	4154
	6154
	4174
8N1
	6174
	4154
	6154
	4174

Obviously, still trying to find the magic boolean logic equation to 
tease out the parity, but you could brute force it with these values and 
only aT would cause you issues requiring looking at CR (7E1 would send 
8d, while 7S1/8N1 would send 0d.
