QUESTION

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?

ANSWER

Yes. You must make a change in the KEILTOOLS.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:KeilC51
KEYONLPT=LPT2    // check for security key on LPT2
