Not only that. The TTL are more frequently 3.3V TTL, and the TTL to
RS-232 converters are supplied from 3.3V and uses a charge pump doubler
and a charge pump inverter. Barely +/-6V. Usually they are designed for,
and use, 100nF capacitors... the less expensive ones :) And a bigger
capacitor would only mean less ripple.
