If all you ever do is transfer your written work from your portable word
processor to your desktop computer for editing then download
WP2DOS.EXE and stop reading. But if your the type that likes to use
your equipment to its fullest then sit back. We will explore an
interesting and seldom published feature of these two great little
Not all computer networking requires big bucks, nor is it necessary to
always load a special program to connect two computers together. For
the most part all you really need is MS-DOS, two machines with
RS-232C ports, a null modem and serial cable.
The Tandy and Citizen portable word processors come complete with
internal telecommunication software, that is easily configurable and very
easy to use. Your MS-DOS computer has the capability of
communicating and transferring to and from other computers via their rs-232C ports controlled from the DOS prompt
command line. In this article we will explore and demonstrate these capabilities., We will also show you how your
Tandy WP2 can be used as a remote keyboard (dumb terminal) to fully control your MS-DOS or Windows 98 (in
DOS mode) computer.
To start, connect your WP2 to your MS-DOS computer using your serial cable and null modem adaptor. Your
RS-232 port is either a 9 pin or 25 pin female connector. Your serial cable and adaptor will have the corresponding
male counter parts. For a detailed description of a null modem you can read more in our article "Transfer Points"
Be sure that the computer system is properly connected to your WP-2 before you proceed. Once you are
connected turn your WP2 or Citizen CBM-10WP , ON, and then boot-up your DOS machine. Once your systems
have initialized, proceed to your portable word processor and following the directions on Table #1
TRANSFERRING FILES TO AND FROM THE PORTABLE WORD PROCESSOR
On your computer be sure that you are at the DOS prompt, and you see a C> or A> prompt. Following the
instructions in Table #2.
Using your Citizen CBM-10WP or Tandy WP2 / WP3 to control your Windows 95 / 98 or MS
Now, comes the fun stuff. Leave the connection set up just as it is. On your WP-2, press [F2]-. On your
ctty aux [ENTER]
This gives the WP-2 input and output of the computer. Press [ENTER] on the WP-2 and you see the DOS prompt.
Now you can execute most MS-DOS commands from the WP-2, type:
ctty con [ENTER]
This returns control to the computer.
This is very helpful if you need to copy or move your transferred document to different directories on your MS-DOS
computer. You can also create new directories or delete old documents while still connected to your computer.
Further, you can remain connected while your continue to write your new document. The distance is only limited by
the length of serial cable and you can easily communicate up to 25 feet.
Try this simple exercise and you will see that these little Zilog based PC word processors are handy tools
