Claim 2:
3. A serial data communication method implemented by a serial data communication device that transmits serial data by a combination of a high level signal and a low level signal, the serial data communication method comprising:
a signal transmission step in which a start bit is arranged on the head of the serial data and a high level signal is transmitted in a prescribed duration immediately before the start bit; a duration setting step in which the duration is set;
a setting reception step that receives a set value of the duration from an external device, wherein the duration setting step sets the duration according to the set value received by the setting reception step; and
a communication establishment determination step that determines whether or not communication with a communication device being a communication destination has been established, wherein the duration setting part increases the duration and decides the duration at a time when communication is determined to have been established by the communication establishment determination part.
