* Modification Log:
* -----------------
* .01 11-27-89 lrd using one more buffer entry than allocated
* .02 11-27-89 lrd throttle on monitor requests
* .03 02-27-90 lrd handle character value links for Joerger
* digitizer (convert to short array for access
* .04 03-05-90 lrd add averaging of entire waveforms
* .05 04-02-90 ba/lrd fix the joerger processing and
* add get_a_byte macro
* fix the determination of buff_size
* .06 04-11-90 lrd make locals static
* .07 05-02-90 lrd fix mdct so that it would remain 0 on the
* pass where the monitors are sent
* .08 05-08-90 ba mdct is never equal to mcnt during record pro-
* cessing, causing some code never to run. Fix
* is to check (mdct==mcnt || mdct==0) to indicate
* first time through an averaging loop.
* .09 07-26-90 lrd fixed the N-to-1 character compression
* value was not initialized
* .10 10-11-90 mrk Made changes for new record support
