Notes: 1.If the installation is running in attached processor mode, the identification code will be OR'd with an X'40' if the activity occurred on the attached processor. If the installation is running ECPS, the identification code is OR'd with an X'80' if the activity occurred in microcode.
2.If the interrupt code (bytes 6 and 71 is OC, the contents of GR 14 are displayed. For all other interrupt codes, the contents of GR 15 are displayed. 3. Bytes 2 through 15 of a code 11 trace record represent a Basic Transmission Unit, sent or received by a 3704/3705. If CONSYSR/CONEXTR are zero, the
BTU was transmitted to the3704/3705. If they are non-zero, the BTU was received. If CONTCMD equals x'noo', this is an unsolicited BTU response.
