[comp.dcom.modems] Anyone willing to teach a little BINARY for S-registers?

I'm having some trouble with a Packard Bell 2400 modem that has
just been put into dial-out service.  It functions perfectly as a
dial-in modem, but seems to be very unreliable connecting to some
modem, while good with others.

I suspect it is the fact that it runs V.22 and when it dials a
modem that doesn't suport this, the PB has trouble negotiating a
connection.  I can't see any command that turns V.22 off, but
someone told me to make the modem dumb by changing one of the
S-registers.  I have been told that you determine the decimal
value to place into the register the following way:

0  1  0  1  0  1  0  1          [the bit settings desired]
1  2  3  4  5  6  7  8          [the bit position]

1       1
2       2       2               [bit 2 on]
3       4
4       8       8               [bit 4 on]
5      16
6      32      32               [bit 6 on]
7      64
8     128     128               [bit 8 on]
              ---
              170               [Sn=170  decimal value]

Is this the way it is done?
