4. Stephanie AllisonEPICS Meeting June, 20034 Port from VxWorks to OSI Kay Kasemir supportive – nice collaboration Most work in driver – not device support Test on Unix first, then checkout on RTEMS Timing and semaphores most work Existing diagnostics great help, web interface useful Function registration for iocsh C++ considerations

5. Stephanie AllisonEPICS Meeting June, 20035 Port from VxWorks to OSI (cont) Not much work for sockets – add TCP_NODELAY option On RTEMS, may need to increase packet limit (max_interrupt_work) from 20 to 40 “connectWithTimeout” is needed in osiSock! Change documentation a little

6. Stephanie AllisonEPICS Meeting June, 20036 Share Source for 3.13/3.14? Use EPICS_VERSION and EPICS_REVISION, mostly in include files to set other macros (code more readable) Setup macros to make 3.13 look like 3.14 Maintain both config and configure directories with the package Maintain both Makefile (3.14) and Makefile.Vx (3.13) Change Makefile to build 3.14 if EPICS_HOST_ARCH is set, otherwise 3.13
