Read Read Read Job Job Job Info Info Info
The Read Job Info command is used to access data from any of the most recent 200 job logs. The argument is the
chronological index
of the job log, where 0 is the most recent job log and 199 is the 200 th most recent.
The date is returned as four-byte packet with each byte holding a two-digit value for (from MSB to LSB) year, month,
day, and day of the week (Monday = 01).
The time is returned as a three-byte packet with each byte holding a two-digit value. Starting from the MSB, the first
byte can be ignored, then hour, minute, and second.
NOTE: NOTE:
NOTE: The argument is an index not a job number. The actual job number will, however, be one of the returned
parameters. These records will match what is reported on the Jobs screen of the ADM.
(See Usage Screen, page 65 , for more details on Job Log)
