This software drives the SBS (formerly GreenSpring) OctalUart family of Industry Pack modules to communicate with a number of RS-232, RS-422, and RS-485 devices. Note that this driver is not compatible with newer IP-OctalPlus modules as they use a different chipset.
The driver uses drvIpac for configuration of the carrier board plus access routines for the SCC2698 octalUart used in the IP modules. The driver implements a standard vxWorks terminal driver making use of the vxWorks tyLib system library.
The following is an example of a startup script (st.cmd) segment that creates and configures IP carriers, OctalUart IP modules, and tty devices. This example is compatible with both vxWorks and iocsh startup scripts.
