  | How do I print backslash \, such as in the following line:
  | 
  | .Dl 0 > Ic "dir scsi/sd@3:0,\subdirectory\"

Backslash (\) is the *roff escape character (by default, and you will
break the world if you change that, though there is a way to do so).

So, you just need to tell *roff to print the escape character, and
a backslash shall eventually appear (and unlike some other mechanisms,
this one is safe, and survives diversions, macro calls, ...)

Referencing the escape character is done using \e

So
	.Dl 0 > Ic "dir scsi/sd@3:0,\esubdirectory\e"

should work.
