Culp,
I think TAM's suggestion to look at the IR program was in response to your "until someone makes a simple software program" remark earlier. Of course without the cable having the program won't prove to offer any particular advantage.
IR is the actual program that's used to communicate directly with the remote. With the cable you can "see" how your remote is set up. It can also be used as a tool to program your remote without doing all the manual keypresses. It can also be used as a tool to look at the signals you may have learned to various buttons. If you are using a lot of learned buttons, that information allows you to make keymoves of a device upgrade (with KM)to thus allow you to dump those learned keys and have that learning memory space back again to use for something else.
The IR program isn't terribly complex. For instance, The "general" tab would list all the 1994's device buttons. If you're familiar with how to manually work your remote, you know for example that you can reassign the device buttons to be something else. That procedure involves several steps, ie, Holding down the P button till it blinks twice, typing in a 9xx code, pressing the button you want to change, pressing the button you want it to be, etc. In IR, You just click on the button you want to change, then scroll down the drop down menue, and select the one you want it to be. On your 1994, you can have the remote "blink back" the device setup code assigned to the device buttons. That involves doing the P and getting 2 blinks, typeing in a different 9xx command, pressing "1" and counting the number of blinks, pressing "2" and counting the number of blinks, etc, etc. In IR, the setup code is given in numeral form, and you can see ALL of the device button's assignment at once, with NO blink counting. No trying to remember what setup code is assigned, all of them are given on one easy to read "chart". Even the VPT settings are listed at the right half, and can be assigned with your keyboard, just like device buttons and their setup codes. You can print that page so you can have a visual reference to it.
With a cable, you can see and make keymoves or build macros on their respective "pages". The devices tab is where we input new device upgrades, and can edit them via our keyboards, or delete one. Adding one is just a copy and paste routine(from KM). Protocol tab is where we can enter NEW protocols, or delete or edit those. The Learned signals Tab lets us look at each learned button, one at a time; all learned buttons will be listed on the left. Clicking on one brings up the data on the right, all about that one button. The "raw data" is the complete huge block of hex data concerning what's programmed in the remote. That page is what IR saves when you save it. We can save it as a .txt file, and email it to someone else, he can load it into His IR program and see how your remote is set up--he'll see exactly the same thing you did.
If you made some type of programming error, he can fix it, save it, email it back to you, and you can upload it to your remote, and all's well.

The list you saw would have a few "readme" files, and the individual "RDF" files for each different JP-1 able remote an rdf has been made for. If you have 5 distincly different ueic remotes, It should have each of the rdf's for each remote, so you can look at and program all five of them. The actual one you'll have to click on to look at IR is the one called "IRexe" Hooking a remote up and downloading it to IR, IR will select the right rdf for you, you don't even have to know which one you need. However, without the cable, you'll have to select the rdf for the remote you want to look at. In your case, the 1994. I THINK, that the 1994 is the one that comes up first when you first open IR, so you probably won't have to select it. If not; just click file>new>select>1994.
Take a look at it, play with it, see how simple it is. What the heck, you can't hurt anything.
