i use 2 multimeter to measure same value also too...
could the problem is about the capacitor value??
coz i using 4.7uF.
if i change to 10uF will get different result?
sorry about that.
i follow this circuit but i using 4 4.7uF connect with max232.
max232 tx output is 4.2V, but when i connect to PC serial pin 2 voltage become 0.3V only.
and PC serial pin 3 voltage actually is how much??
i using multimeter measure is -10V when connect with my max232 become -9V...
