This paper introduces the development of RS232 communication driver under EPICS based on Linux platform.The work is based on the control system of BEPCII experimental electron gun.OMRON CQM1 PLC is taken as the example device.Its EPICS driver is analyzed in detail,including the driver's hierarchical structure and particular implementation codes.The plan of developing EPICS device support programs of other devices based on this universal serial port communicat ion driver is in progress.
Key words： EPICS; serial port communication; device driver
