SerialSendBytesTask

OpalTask: send raw (hex-encoded) bytes to an open session.

Detailed description

Carries the serial.io permission scope with confirmation policy EveryCall. Complements SerialSendLineTask for binary protocols where appending a line ending is wrong. The hex string tolerates internal whitespace; an odd number of hex digits or a non-hex character is a parameter error.

Refused while a drip-feed run is active on the same session.
