This in in response to an article about the compatibility of the AT&T 605 terminal and the AT&T 6386, running multiple DOS applications under UNIX. The 605 BCT is designed to automatically operate correctly with the 6386 in both UNIX and DOS. The 605 in DOS sends scan codes to the 6386. The scan codes are passed to the DOS programs in the same manner as a PC keyboard would pass key codes. The note in the 605 Simultask and VP/ix configuration files regarding a potential mapping problem is -not- true and has been removed from the current releases of both the Simultask and VP/ix files. In UNIX you set the terminal option for a "Normal" keyboard. Simultask takes care of switching the terminal to the PC mode when you run DOS and back again when you return to UNIX. UNIX will only recognize the Normal mode. The 605 has been designed to work as an asynchronous terminal, and also as a terminal for use with the AT&T 6386 running DOS applications. The 605 is compatible with the 6386, VP/ix, and Simultask 386.
