µVISION: USING DONGLES WITH LPT2 OR LPT3
Information in this article applies to:
We have a device programmer that uses the parallel port. This programmer will not work if the dongle is connected in line with it. Can we connect the dongle to LPT2?
Yes. You must make a change in the \KEIL\TOOLS.INI file to specify the LPT port for the dongle.
The KEYONLPT identifier specifies the LPT port that is used for the Security Key. For example:
[C51] PATH=C:\Keil\C51 KEYONLPT=LPT2 // check for security key on LPT2
