This is a driver for the Acromag IP520 EIA/TIA-232E and IP521 EIA/TIA-422B (supports EIA-485) Industry Pack communication modules.
The driver uses drvIpac for configuration of the carrier board plus access routines for the underlying dual ST16C554/654 quad UARTs used in the IP modules. The driver implements a standard VxWorks terminal port 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, IP520/521 modules, and tty devices. This example is compatible with both vxWorks and iocsh startup scripts.

When running EPICS base 3.15 or higher, the iocshLoad command can be used with the ip520.iocsh script included in this module's top-level iocsh directory. The following shows an example of such a use.
# Initialize the drvIpac carriers.
# -------------------------------
# carrier#0
ipacAddMVME162 "A:m=0xe0000000,64 l=3,2"
# carrier#1
ipacAddVIPC616_01 "0x6400,0xB0000000"
# carrier#2
ipacAddTVME200 "602fb00"
# Initialize an ip520 module called MOD0 that's located in slot A of
# of the first initialized carrier (MVME162), and then create 8 tty
# ports labeled /tyGS/0,0/0 through /tyGS/0,0/7 on that module.
# Also tell the script that you will be initializing up to 5 more modules.
iocshLoad("$(IPAC)/iocsh/ip520.iocsh", "INSTANCE=MOD0, INT_VEC=0x80, CARRIER=0, SLOT=0, MAX_MODULES=6")
# Initialize the ip520 module in slot B of the MVME162, the tty ports
# created will be labeled /tyGS/0,1/0 through /tyGS/0,1/7
iocshLoad("$(IPAC)/iocsh/ip520.iocsh", "INSTANCE=MOD1, INT_VEC=0x81, CARRIER=0, SLOT=1")
# Init two IP520 modules from the 1st SBS VIPC616_01 carrier; the 1st
# module is in slot A, the 2nd module is in slot C.
