The local twinaxial workstation controller maps keyboard data received from a workstation into EBCDIC values corresponding to the keyboard ID configured for that workstation on the system.
Multiple languages are supported by using a separate keyboard mapping table to handle each unique combination of national language version and keyboard for each workstation attached to the system.
The amount of storage available within the twinaxial workstation controller for mapping tables is limited and restricts the total number of national language versions that the workstation controller can simultaneously support. Depending on the mix of languages and types of keyboards, the twinaxial workstation controller can support several different national language versions simultaneously (in addition to U.S. English, which is always available).
The twinaxial workstation controller supports the following types of IBM® keyboards:
The sum of the computational factors for a language and keyboard type must not exceed 22 for the twinaxial workstation controller. The following table shows the computational factor for each language, KBDTYPE parameter, and keyboard type.
Each workstation controller supports a maximum number of languages at the same time, regardless of the keyboard types. This maximum number is in addition to the US English support.
