 I was just wondering if anyone using CaPython has experienced any problems setting the individual bits on a channel such as using:

ilcControlChannel_B8 = CaChannel()
ilcControlChannel_B8.search('control_mbbo_direct_' + str(ilc) + '.B8')
ilcControlChannel_B8.array_put(1)              ilcControlChannel_B8.pend_io(0.1)

setting the bits B7 and below (0-7) seem to work without problems, but I'm getting an exception using bit B8 (haven't tried anything from 9-15). 

  I have a short wxPython application with a list of ILCs and several status flags (set online, offline, boot request, load request, reboot, clear error counts) read from various channels. The control channels seem to work but when I try and set the "Clear Error Counts" (which is the only bit in the upper 16 bit region) it gives an exception and the crate hangs it seems.

Any suggestions?
