Thanks Chris, I know you and I have talked about modbus and classic
ladder before. I did find a version on source forge that is version
0.8.2. How would I go about getting version 7.124 to work with the
current version? Are there a list of instructions some where? How do I
get from CVS?

I agree. Every time I have mentioned it the discussion ends up with
"It's a bad idea to run servos from modbus". I couldn't agree more but
it could be very usful for simple digital I/O very safely.

Rather than writing "another" serial interface why not use Modbus and a

For "slow I/O" like coolant, a device attached to a serial or USB port
can be appropriate in emc2. You'll probably have to write your pic
firmware and an emc2 "hal" driver in tandem, since there's not an
established protocol for this (unlike, say, step&direction signals).
Conceptually, the PC sid
Hello,
has somebody allready written a hal driver for a serial IO interface? Till now
I use a serial interface with a pic and 32/16 In-Outputs with Emc1 and tclsh.
A nice example in C would also be helpfull. Is there anywhere an example for
a c driver in user mode(not realtime) ?
Thanks
Malte
