RUI Rules

  1. To allow the RUI application to handle the compression and decompression of data:
    • The RUI application receives the BIND request that has bits 6 and 7 of Byte 25 set to indicate compression is offered or requested.
    • The RUI application should return the positive BIND response with bits 6 and 7 of Byte 25 set to indicate "offered or mandated compression accepted".
  2. To allow Communications Server to handle compression on behalf of the RUI application:
    • Use the Communications Server SNA Node Configuration utility to indicate that the node supports compression by doing the following:
      • Select Configure Node
      • Select Advanced
      • Set maximum compression level supported by node to RLE
    • The RUI application receives the BIND response with bits 6 and 7 of Byte 25 set to indicate compression is offered or requested.
    • The RUI application returns the positive BIND response with bits 6 and 7 of Byte 25 set to indicate "no compression". Communications Server intercepts and modifies the BIND response, then compresses and decompresses the data to the host.
