Re: Question about modems

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.
