Job sticks under Macos

Hi,
I have everything working, running a tinyG. I can send a file from Coolterm and it finishes. Everything Laserweb looks fine except when I start a job it will only execute several of the commands before it freezes. Could this be a flow control issue? At one point I thought it was not having CTS flow control set in the TinyG, but it still does it. How is flow control in Laserweb set: does it just inherit what the port was set up for?
Thanks and would appreciate any help.
Curt
