288-053 AIX Access For DOS Users and IBM X-Windows For DOS
AADU PARTICIPATION IN AIX AS INTELLIGENT WORKSTATION:
The PC, XT, AT or a PS/2 may be attached to an AIX host
system on an Ethernet LAN, Token-Ring LAN, or asynchronous RS-232-C connection.
Upon initialization, the AIX Access host menu lists the available AIX DOS
server. The user selects the desired AIX DOS Server and enters a
valid AIX login name and password. When the connection is established,
a DOS prompt (A>) appears. The user may invoke DOS and AIX programs
and connect input and output using named pipes from either AIX or DOS programs.
SHARED VIRTUAL FILE SUPPORT: AADU
provides the DOS user with virtual disks that present the entire AIX file
system space as if it were locally mounted. DOS references to files
on these "volumes" are carried out in the AIX system. These files
are shared by DOS and AIX. DOS application programs and data may
reside entirely or in part on these shared volumes. The resource
sharing services appear native to DOS. Conversion routines permit
AIX and IBM DOS utilities and applications to pass text data files between
DOS and AIX naming conventions,
including directory naming,
are mapped to one another within the AIX DOS Server/User system in
way familiar and acceptable to both environments.
VIRTUAL PRINTER SUPPORT: AADU provides
access to AIX system printers by allowing the user to reroute output selectively
to AIX systems. AIX requests can be issued through use of the print
screen (PrtSc) key, by the DOS copy command to the remote print device
(LPT1), or from an application program. Only those characters printable
by the AIX printer are supported.
TERMINAL EMULATION: AADU emulates
an ASCII terminal, providing the keyboard and program interface characteristics
of a DEC VT100.
Terminal emulation mode may be
started from DOS at any time. If desired, the user can switch back and
forth quickly between execution of DOS programs and performing work as
a standard AIX ASCII terminal.
While a terminal session is inactive
on the workstation, it
remains active in AIX, so background work continues. Output to
workstation is buffered and displayed when the terminal session is
When in terminal emulation mode,
the user may invoke any AIX
functions or programs available to the asynchronous terminals on the
attached AIX systems.
PC-BASED VI EDITOR: For AIX users
with extensive editing requirements on AIX files, a PC-based vi editor
is included with AADU. This editor is compatible in syntax with the
AIX vi full-screen editor. Through the use of this editor, the AIX
user is able to perform most editing on the IBM personal computer, unloading
one of the most CPU-intensive tasks to the intelligent workstation.
The files created with the PC-based editor can be used directly by AIX.
