SCO OpenServer supports terminals, such as the Wyse 60 and the H-P700/44, which have a ``PC-compatible'' (scancode) mode.
The mscreen(M) (terminal multiscreen) utility can be used on scancode-compatible serial terminals, but you should note that when it is used on a Wyse 60 terminal, the screen must be refreshed after a screen switch. This is because the Wyse 60 does not support hardware page switching when in PC-compatible mode.
You should also note that when running under mscreen, although the terminal itself may be in scancode mode, the login sessions are running on pseudo-ttys, which receive ASCII data from the mscreen utility. The effect of this is that applications that normally run in scancode mode, such as Microsoft Word, will actually start up in ASCII mode.
telnet or rlogin sessions to a remote host also transfer ASCII data via a pseudo-tty, even if the physical terminal or the console in use is in scancode mode.
The usemouse(C) utility can normally be used on a serial terminal in scancode mode, using the same default map file or application-specific map files (in /usr/lib/mouse) as the console. However, when running on a Wyse 60 terminal in PC-TERM mode, use the same map files as when running on a Wyse 60 in native mode.
