# EPICS: GPIB Support Known Problems

## Release 1-2

### drvVxi11

- SDC and GTL are not implemented.
- Direct connection to ethernet device:

  The only ethernet device tested so far is a TDS3014B scope. The st.cmd file in iocBoot/ioxhost shows the drvVxi11Config that is used to talk to this scope.

  SRQs did not work via the ethernet port even though no errors were reported. However, when the TDS3014B was accessed via the E5810 LAN gpib server SRQs did work.

  Until we get more experience with ethernet VXI11 devices it is not known if we are properly handling such devices.

### vxWorks

- NI1014
  - SRQs dont work
  - restartLink does not work

### Solaris

- E5810 SRQs are slow
- E2050A doesnt work

### E2050A

SRQs are slow on linux

### winXX

Until the epicsShareFunc, etc junk is added to all externals the support will not work on windows.

### Future

- Should GTS be implemented?
- The shell commands should be checked for consistancy, in particular the time arguments should have consistant datatypes and unite.
- Should BBGPIBIO support be removed?
- GI doesn't work with drvTermiosTty. It must be extended to support message terminaters.
