Okay... NOW we're getting somewhere... Look around on the Tech 2 Forum...
@Mooseman has a Link to where you can download a decent "Software Dongle Crack" that may supersede what you have installed right now. Personally... I prefer using the Physical Plug-It-In USB Port "Dongle" vs. using "The Crack" any day, as mine has proven to be the most reliable extra necessary piece of hardware for my Tech 2 Set-Up.
Basically the USB and "The Software Crack" provides something similar to a "Permission Slip" that allows TELNET- TTY Communications to pass between the Handheld Tech2 ...and the Old "Tech-Line" Fancy Dealership Terminal Machines from 1996 and later. The image I stole from your own image posted earlier ALSO shows a Serial Communications-To- (9) PIN DIN Plug circled in
RED as yet ANOTHER Physical Piece of Hardware from The Good Ol' Days that...
believe it or not... I've seen and used as proprietary Adapters that were ALSO Called "Dongles"
(God ...I HATE That WORD!)
Anyways... Unless you already have one of THESE...you can purchase an inexpensive Kit from aliexpress.com that
Includes either a 2 or 3 Disk Set of TIS2000 CDs AND a USB Port DONGLE... that authorizes your Windows TIS2000 Software...to work:

One Last Precautionary Note...
If you decide to go the USB Dongle Route... It will make your life a LOT easier if you just Install a FRESH TIS2000 Software Suite...and FOLLOW THE INSTRUCTIONS AS TO WHEN TO PLUG IN THE USB DONGLE WHEN THE APPLICATION ADVISES YOU TO DO SO...
You Can NOT have BOTH the Software Dongle Crack AND the Physical USB Dong;e Plugged in ...simultaneously... The Non-Obvious Conflict will occur...and the Software Error will give no clear indication as to how to solve the SW v.s HW Conflict.
