c0c2b5e3a9 Post key actions to the nominated serial line. 
Albeit that I'm still thinking through whether I want the option of including a clock on Serial::Line. It'd be natural in one sense — there's already one built in — but might weaken Serial::Line's claim to be a one-stop shop for both enqueued and real-time connections without a reasonable bit of extra work.
