I've an old DOS program (1992 installed) that requires a dongle to work. I recently did a backup of the harddrive, the software worked fine after rebooting but when it was moved to its work location and rebooted it failed to find the dongle on the parallel port. The parallel port prints fine.
The company no longer exists who developed the software is there
1. Any option to get this running again?
or
2. Modify the dongle.
I have another dongle for another computer but it is different serial number and only works with its own computer. There is a battery in the dongle.
3. Could this be removed without causing the dongle any harm.
The Dongle is Dallas Semiconductor.
Thanks...

What did you do, exactly? You moved the hard drive? From what to what? What O/S(s) are involved here?
If the HD was moved between computers, the I/O address of the parallel port may not be the same in both systems.

The harddrive (DOS) was moved to a remote USB copier where we able to copy the data to another computer harddrive (Windows XP). The program did work after reinstalling the harddrive.
I did try to install a ZIP drive so we could use this as a backup tool but this did not work as it failed to find the device. The computer was installed on site and then the problem arose.
If so, it's very probably the Hardware Abstraction Layer (included in win NT and onwards) that doesn't allow proper access to the hardware, which makes it impossible to read the parallel port dongle correctly.

The problem is it is now looking for dongle XXXXXXXXX and then can do no more. The dongle is installed as before as it is labeled.
Thanks for your time.

If it is another computer - check I/O address and IRQ line that is used for the LPT port you are using; I guess it must be the same values in both computers (BIOS settings, or at least info in the BIOS system summary screen).

I tried another computer and it had the same problem, although I did not look at the settings. How do I check the I/O address and IRQ line.
