On the T1600 there is a register (S59) which enables the suffixes on the
CONNECT message.  The documentation for the registers says that the default
value is 0 and the register can have any value in the range 0 to 15.  But
there is no further explanation of what the values mean.

The format of the connect message is:

     CONNECT (X cmd speed)/(link)/(compression)/(other speed)

where the value in parens is filled in and the slashes separate the
various values.

<Speculation mode on>

There are thus 4 suffix fields in the connect message.  The maximum value
for S59 is 15 decimal or F hex, which is 4 bits!  So the S59 value appears
to be a bit mask of which suffix fields to include in the message.

Is this correct?
