psc_status is an obsolete MAS application which was used to communicate with the PSA switching supply designed and supplied by UBC.

psc_status decodes the information sent back from the MCE in response to a psc_status command. Usage is:

 psc_status -h
 Initial options (MAS config):
       -c <hardware file>      override default hardware configuration file
       -m <MAS config file>    override default MAS configuration file
       -i                      read psc_status as ascii from stdin (no MCE)

The 9 x 32b words returned in response to a psc_status command are described in psc_status.h as:

static char psc_data_blk[PSC_DATA_BLK_SIZE] = "";
