The 3270 remote attachment feature allows a 3270 SNA controller or a 3274 emulating device to be attached to an iSeries™ server.
Some applications for the 3270 that use data description specifications (DDS) might require programming changes. An operator at a 3277, 3278, or 3279 data entry keyboard can use most features and functions as a similarly configured and authorized 5250 workstation. The attached unit has the same capabilities and limitations as any remote 5251, with the following exceptions:
In addition, if a write operation is requested by the user application to display an error message, a read operation should immediately follow the write operation for the remote 3270 display to allow resetting of the error message. A read operation following a write operation of an error message should be used by call applications regardless of the type of target display. If a read operation does not immediately follow the write error message requested by the user application, remote 3270 displays might overlay the error message before it can be read by the user.
