This document describes changes made to Peregrine McGehee's vxWorks driver for the GreenSpring Octal RS232/RS422/RS485 IndustryPack modules since this driver was merged into the unbundled EPICS ipac support area. Version numbers refer to the release of the ipac support software as a whole. The earliest version appears at the bottom, with more recent releases above it.

Version 2.3

Modified documentation to indicate non-support of the new IP-OctalPlus module family, which uses different UARTS.

Added Burkhard W. Kolb's RebootHook routine to turn off interrupts.

Version 2.1

Updated due to changes made to drvIpac, and also actually tried it out for myself - got some interrupts but I haven't done a full test.

Changes:

• Use ipmIntConnect to attach the ISR.

Bugs fixed:

• Now works with the ipmv162 carrier driver - the interrupt vector register was being accessed at an offset from the I/O space, which works on GreenSpring carriers but doesn't meet the IPAC specification. The register is correctly accessed in the IP memory space, which means that this must be mapped in.

Version 2.0

First version containing this driver, ipac support is now structured as an EPICS R3.13.1 <supporttop> application.

Added:

• This driver software and these release notes.

Bugs fixed:

• Gcc compilation warnings attended to.
