REFERENCE INFORMATION
SSLBP
DISCOVERY SEQUENCE
SECOND PART, READ PROCESS DESCRIPTOR AND MODE DESCRIPTOR
RECORDS:
11. For each PTOC entry acquired in the previous step:
12. Remote read byte at PTOC+0
12. If byte is 0xA0, proceed to step 16, reading process data descriptor
14 If byte is 0xB0, proceed to step 25 reading mode descriptor
15. If byte is neither, there is a error
16. Remote read byte at PTOC+1 This is DATA_SIZE
17. Remote read byte at PTOC+2 This is DATA_TYPE
18. Remote read byte at PTOC+3 This is DATA_DIRECTION
19. Remote read long at PTOC+4 This is PARAM_MIN.
20. Remote read long at PTOC+8 This is PARAM_MAX
21. Remote read word at PTOC+10 This is PARAM_ADD (not used normally)
22. Read UNIT_STRING starting at PTOC+12
Initialize CharPointer to PTOC+12
repeat (remote read byte at CharPointer, increment CharPointer, if byte is 0: done)
23 Read NAME_STRING starting at CharPointer
repeat (remote read byte at CharPointer, increment CharPointer, if byte is 0: done)
24. Repeat with next PTOC = step 11
