Hi everybody,

We need to control insrtument using RS-485 communications. We use a
GreenSpring IP carrier (VIPC610) with an IP module (TIP865 from Tews
DatenTechnik). The driver is a VxWorks device driver for TIP865 serial
IP.
But we have a problem of interrupt. When the instrument send info to the
VME, the CPU is blocked before we could read the info (the interrupt
vector for reading doesn't pass). The system seems to keep an old
interrupt on the bus, that prevents following routines to start.
Is there someone who met such kind of problem.
Thanks for your advices.
Regards,
Fred
