Hi,
I am not sure if I have solved the problem yet. Last week I started having some other weird things happen and with the help of Bob @ Practical Micro we narrowed the issue down to a faulty PMDX 131 board. They sent me out a replacement and I installed last Friday. Ran it for a coule of hours and all seems well.
As I have said before, I don't really know where/which 'buffer' Mach is referring to in the error message. So, it's kind of conjecture on my part but I would imagine the PMDX has a buffer (or maybe it reads from the buffer on the PC runing Mach?) and I'm thinking that's where my problem was.
Runing the machine this week should be telling. Thanks for the help!
Regards,
Sid
