Please send the following:

- Complete output when the IOC boots and runs for 10 seconds or so after iocInit.

- Output of the command
  asynReport 10 myPort 
where myPort is the name you assigned to the motor controller port you created.

I have followed the documentation in the motor record to setup the IOC for the MCB-4B controller board. Using the IO traces I can tell that communication with the board is happening (there is a constant polling of position and responses from the board, etc.), but whenever I try to change a value for a motion field I get the following:
