DDM error codes

These error codes are included in the FFDC dumps (L in the sample dump output) that identify DDM error conditions. These conditions might or might not be defined by the DDM architecture.

• Command check codes
  If FCT+ (SPACE- 02) contains 1254 in bytes 3 and 4, look for one of these codes in byte 6.
• Conversational protocol error code descriptions
  If FCT+ (SPACE- 02) contains 1245 in bytes 3 and 4, look for one of these codes in byte 6.
• DDM syntax error code descriptions
  If FCT+ (SPACE- 02) contains 124C in bytes 3 and 4, look for one of these codes in byte 6.
