Why does OS2MORE.COM give a SYS0447 in an xterm?
This is a program which silently assumes it has access to the keyboard and the screen: it uses functions from KBDCALLS, MOUCALLS, or VIOCALLS. There are more programs of this kind, for instance: most *.COM in \os2, ATTRIB.EXE, BACKUP.EXE, CACHE.EXE, EAUTIL.EXE, FIND.EXE, HELPMSG.EXE, LINK.EXE, LINK386.EXE, PATCH.EXE, PSTAT.EXE, REPLACE.EXE, RESTORE.EXE, SETBOOT.EXE, SORT.EXE, SPOOL.EXE SYSLEVEL.EXE, TEDIT.EXE, TRACE.EXE, UNPACK.EXE, XCOPY.EXE, XDFCOPY.EXE, but also unfortunately TELNET and FTP, and some others; infact, almost any 16 bit application is a possible candidate.
