Title: Serial transmission apparatus, information processing apparatus, and serial transmission method

Abstract: A serial transmission apparatus, which transmits data through a serial communication line, includes a transmission unit configured to transmit data stored in a transmission data buffer to a transmission destination apparatus, a time-out detector configured to detect a time out when a response to the transmitted data from the transmission destination apparatus is not received within a specified period of time, a recovery state detector configured to detect a recovery state representing that the serial communication line is in a link recovery process, and a retransmission request unit configured to request the transmission unit to transmit again the data which has been stored in the transmission data buffer when the time-out detector detects the time-out or when the recovery state detector detects the recovery state of the serial communication line.
