            Note: Each register "pair" holds the value for each setting.
            To set a value, divide the setting by 256. The integer goes
            in the second register, while the remained goes in the first.
            (A setting of 516 would convert to 2 Remainder 4, and could
            be set by sending ATSC0=4SC1=2 to the modem.) Settings are in
            1/100ths of a second. Setting SC0=25 & SC4=25 allows FAST
            BUSY to also be detected as BUSY.

            restore the modem to Asynchronous Mode.

            2. Connect modem to an Asynchronous Terminal with the DTR
            signal (line 20) disabled (a "break-out" box works very
            nicely for this) and issue the configuration you want or AT
            &Q(0,5-9) &W to return the modem to Asynchronous Mode.
