Nnncodes - IBM 3708 Description

NNN Codes
The NNN codes appear in the Session Status field when one of the following occurs:
• The host generates an invalid SNA data stream, which is indicated by a Program
Check (pC
nnn).
• The communication link with the host fails; which is indicated by a
Communication Check (CC
nnn).
When the host application or system recovers, the status line is automatically
cleared. If it is not cleared, contact the system administrator. Table 4-8 shows the
NNN codes that appear in the Session Status field.
