Hi I do have these problems. It is because the processor chip os too fast that the program Pcbug11 cannot be used on fast processor. Later i used Winbug and Jcbug11. Winbug can be used on winNT or win98. Sometime it oso give communication error. Jcbug11 i didnt try as i oso give me problem on communication error, It is either you used PC of processor 486 or slower; Or you can try using Xload or MicroLoad to download to you microcontroller. they are both available in the website of technological arts. good luck on trying, Regards HuiChen micro controller <> wrote: Hi to all, I'm using PCBUG11 to program a 68HC11A1P.

I tried connecting it to the other unused Rx on the MAX232, then NOT CONNECTED, then to GND via a 5Kohm resistor ('cause I saw that the MAX232 has a 5K resistor to GND on its Rx input, and the corresponding Tx output is unused...) It's really disappointing having to try all combinations without success!! :(:(:( Are there recommendations/check ups that can help ?
