  • I can confirm that this capacitor layout simply does not work for the very common (pin-compatible) max232a subsitute, the sp232acn. Connecting pins 2 and 6 via a capacitor instead of to Vcc and Ground causes very unreliable operation at 38400bps, with about one out of ten characters getting through correctly.
