CAN
---

True - there's currently a VxWorks CAN 'driver' existing for the 
CAN-IP module. At least two CAN modules talk to each other. This work is 
done in anothr group at DESY. We will continue with this work which 
probably will start in autumn. If we could work together with othrs I would 
be really interested. Specially implementing the CAN-services is something 
which needs more efford and should be shared. 
There is another institute in Germany using CAN on VxWorks they are not 
EPICS oriented and their code might come from a commercial company.
I could ask ...

RS 232
------

We run two protocols on RS 232 using the Greenspring IP module.
I have to check but I am afraid that the VxWorks-driver origially was 
purchased from a german company.
But the EPICS device support is DESY-code.

TCP/IP
------

We have written a device support using UDP communication for the FNAL 
'classic Protocol'. If this help s let me know...

Our current developments and drivers will be soon made available on our WWW 
server.
