EHLLAPI Support in VT and NVT Modes

HostExplorer supports the EHLLAPI interface while in VT and NVT (Network Virtual Terminal), or ANSI terminal modes. This allows your application to interact with a front-end system without requiring a new interface to work with the ANSI-terminal portion of the emulator.

While in NVT mode, only a subset of the EHLLAPI functions is supported. This is mainly because the NVT screen does not contain 3270 information and does not have a concept of fields.

EHLLAPI no longer supports extended return codes for NVT mode. To enable support for extended return codes, add the following line in the EHLLAPI.Settings section in the HOSTEX.INI file:

: [EHLLAPI.Settings]
Enhanced RC = On
