Maxess 1.2.1

The only request unit (RU) size Maxess sends for the secondary
logical unit (SLU), inbound to host, is 256 bytes.   The 10th
byte of the 3270 (LU 1,2, or 3) bind session parameter should be
hex '85'.  If the RU size is less than 256 bytes, then a negative
response will be returned.

The response unit (RU) size for the primary logical unit (PLU),
outbound from host, can be between 64 and 2048 bytes.
Recommended is 2048 bytes.   The 11th byte of the 3270 (LU type
1,2, or 3) bind session parameter would be hex '88' for 2048
bytes.  If the RU size is less than 64 bytes or greater than 2048
bytes, then a negative response will be returned.

Only the Host personnel can make changes to the bind parameters.
