D-Series and C-Series Compatibility

D-series EM3270 and EMCOM adhere to the rules and conventions that govern network

communication and compatibility between D-series software, C-series software, and

B-series software.

D-series EM3270 and EMCOM run only on the D-series operating system. However,

with restrictions, they can communicate with C-series operating systems.

C-series EM3270 and EMCOM can run on either C-series or D-series operating

systems, but cannot make full use of the high PINs of the D-series system.

For additional information on high PINs, low PINs, and the advantages of the D-series

operating system, refer to the Introduction to D-series Systems.

Networking Restrictions

There are restrictions on how D-series EM3270 and EMCOM and processes on

D-series, C-series, and B-series operating systems can communicate. These restrictions

follow the general rules of compatibility between D-series, C-series, and B-series

operating systems. Table L-2 summarizes the possible hybrid network configurations.
