#165425 - have you perchance .. Responding to: ???'s previous message |
And more interestingly when I put MAX232 chip from my older tested board everything works fine.
That suggests MAX232 ic is faulty. But I tried out by changing almost dozen Ics. But system works with only with the older Ic. have you perchance a MAX232A working and a MAX232 not working. One takes 100nF, the other 1uF caps. Erik |
