- The original question was an LU Type 2, or 3270. Both the 3274
- and 3174 manuals note otherwise for an LU_Type 2.
-
- If the SLU receives an ACTLU, and ERP is not specified, the SLU
- terminates any EXISTING sessions between that LU and a host
- program. The SLU returns a +RSP to the ACTLU and the SSCP-LU
- Session is re-established.
