Hi, since last week the latest version (0.2) of a serial port programmer driver for Linux is available at: http://www.thp.uni-koeln.de/~rjkm/linux/serp.cc Reading and fuse programming support has been added since the first release. There is also some experimental code for the 24C65 EEPROM but for me only reading works. For writing the voltage levels are probably too much off the specs!? Because many people accessed the file on our web server I would really be interested if it works for anyone. If I created network traffic for something that only works on my hardware, please tell me!
