Commands such as c1 pt and sdi12 pt will cause a Wombat to hang if they are run from a downloaded script because there is no way to issue the ctrl-D to exit passthrough mode. Other commands such as c1 pwr or sd log also make no sense in this context.
It would be good to have a way to either mark commands as being interactive-only and/or have a variable that says a command is being run as part of a downloaded script so the command code can decide whether to run or not.
