How to send serial string with nonprintable chars?

[jchuchla]

What is the proper syntax for an action in a rule to send a string out the serial port with non-printable characters? I can use "serialsend this is my text" and on the port, i see "this is my text" But what if I need to send a series of bytes that aren't necessarily printable ASCII chars? For example, I need to send the 7 byte string 08 22 00 00 00 01 D5.
