Saw wave on RS232 Tx ?
I am using a MAX3232 for RS232 line driver and basically it works. But, when examining the Tx line with a scope, it is observed that it has the shape of a saw wave with amplitude of about 250-300mV. This happens both at the positive as well as the negative voltages. Voltage to the MAX3232 is 3.3v and all caps are 0.1uF (as per spec).
Why is this? What could be wrong?
