Hi, Darrel

Using ARRAYWRITE for such uses causes me some trouble when using STR\n ...

as Manual states on p.54

The length is determined by the count ,less than 256 OR when a "0" is encountered in the string
quite annoying for sending numbers as strings ... as you can see it in the DT_USB Demo you showed us i.e. . ( in the right window, strange numbers appear ... )

do you have a fix or turnaround for that ???
