Abstract
A method includes receiving inputs including a serial communication protocol specification and serial port settings associated with a serial communication channel. The method includes determining a transmission speed, a request size, and a response size of the serial communication channel based on the inputs. The method includes determining a timeout value corresponding to the serial communication channel based on the transmission speed, the request size, and the response size. The method includes automatically setting a timeout parameter for the serial communication using the determined timeout value. The timeout parameter defines a length of time between a start time of a transmission of a request through the serial communication channel and an end time of waiting to receive a response. The method includes in response to not receiving the response before the end time, determining that a first device is not connected to a second device through the serial communication channel.
