You can get a null-modem cable from RadioShack or your favorite computer store for around five buck$. That is the easiest way, going from one serial port to the other. If you have DOS 5 or higher on your Zenith, then you have everything you need to run Interlnk/Intersvr. That is very to set up and run. You will want to run the Interlnk app on the Zenith, and the Intersvr half on the Austin laptop. First, you'll have to add a line to your config.sys file. Do you have a monitor you can borrow for a few minutes, so that you can edit the config.sys? If so, then procede as follows:
-Boot up the Zenith with the external monitor attached.
-On the Zenith, type EDIT CONFIG.SYS
-When the editing screen comes up, use the arrow keys to scroll down to the bottom of the file, then type DEVICE=C:\DOS\INTERLNK.EXE
-Hit alt then F then X then Y to exit and save the file. At this point, you no longer need the external monitor.
-Shut down the Zenith, disconnect the monitor, and install the null-modem cable to both laptops.
-Now, boot up the Austin first, then the Zenith.
-On the Austin, type C:\DOS\INTERSVR then hit enter.
-After a few seconds you should see a message on the screen telling you about your new drive letters.
Now, just use those new drive letters as you normally would. See how easy? Try it. Lemme know if any problems.
