Asyn Driver was applied for PC/104 IOC serial communication systems at Jefferson Lab. We chose the ines GPIB-PC/104-XL as the GPIB interface module and developed the low lever device driver that is compatible with the asynDriver. Instrument device support was created to provide access to the operating parameters of GPIB devices. Low level device driver for the serial communication board Model 104-COM-8SM was also developed to run under asynDriver. This serial interface board contains eight independent ports and provides effective RS-485, RS-422 and RS-232 multipoint communication. StreamDevice protocols were applied for the serial communications. The asynDriver in PC/104 IOC applications provides a standard interface between the high level device support and hardware level device drivers. This makes it easy to develop the GPIB and serial communication applications for PC/104 IOCs.
