MFS device descriptor format and parameters

MFS device descriptors are used by the MFS Device Characteristics Table (MFSDCT) utility.

The MFSDCT utility updates screen information, for example 3270 screen sizes and feature information, in the DCT and generates new MFS default formats without system definition.

You use MFS device descriptors to define characteristics of terminals added dynamically that have different characteristics from statically defined terminals.
