Thank you Microchip! This new driver was a long time coming, but now that it here, I can finally format my WIN98 PC and load Windows 2000 Professional. I just programmed a 12C509 and had no problems what's so ever. Thanks Ray Doerr -----Original Message----- From: Darrel Johansen To: PICLIST@MITVMA.MIT.EDU Date: Friday, February 19, 1999 3:49 PM Subject: NT PICSTART Plus Drivers Two versions were posted. The one posted yesterday (file date: 17Feb) suffers from a crash if the COMM port is not set up properly in NT. The one posted today (file date: 19Feb) does not crash. There have been reports of some difficulties in setting up the COMM ports on NT. Some users of Win 95/98 have also experienced this problem and there are a series of troubleshooting tips in the PS+ User's Guide and the on-line README.PLS text file. Directions for using this driver: 1. Download MPPLUS.ZIP from http://www.microchip.com/10/Tools/picmicro/program/picstart/index.htm 2. Unzip 3. Copy the new unzipped MPPLUS.DLL into your MPLAB v4.00 installed directory (this driver only works with MPLAB v4.00). 4. Set up COMM port set up on your system 5. Run MPLAB and select correct COMM port for PS+ Report troubles to the Microchip Development Tools conference: http://tech.microchip.com/~DevTools PRO MATE and MPLAB-ICD NT drivers coming in March.
