  I am having a small problem with the RESULT values I get when I call
my FOSSIL.

   I called the request status [AH=03h] to check out what was happening
in the com port, I received 6030h back which is correct:

  What I want to do is translate this HEX value into BINARY so I can
check what `each bit' means:

  For example:

  6030h =  0110000000110000 in base 2

 This matches up to:

  from left to right:

  Position 5: indicates `clear to send'
  Position 6: indicates `data set ready'

 Etc , etc ..

 Now ALL I need to do is somehow convert this 6030h number into BITS
because EVERY position is important to me.  Does anyone know of a quick
and painless way to do this?

   I was playing with BIT FIELDS, but this did not seem to work.

 It would be nice if i could do something like:

    struct modem {

         unsigned clear_to_send : 1;
         unsigned data_set_ready: 1;
            .
            .
         unsigned time_out :1;
      } code;                        <-------------+
                                                   |
 then put the 6030h into base 2 and throw it into code . Can it be done?

  Is there an easier way?

                                     Mark Longo
