Hardware and software requirements

In order to use extended codes for LMS, the following prerequisites must be met:

• software product XHCS (optional subsystem XHCS-SYS)

• software component VTSU

The software product XHCS (eXtended Host Code Support) is required for generating extended codes in the host and for transmitting data between the host and the data display terminal. A detailed description of the principles and functions of XHCS as well as a list of code tables and names of standard codes are provided in the “XHCS” manual ([15 (Related publications)]).

As hardware, it is necessary to have 8-bit data display terminals in order to input and output extended character sets.
You can use the software component VTSU to test data display terminals for 8-bit capability.
