Apparently the switchar can be read using INT 21H with AH=37H, AL=00H.
The switchar is returned in DL (I have not tried this).

But, why read the switchar at all ?   Just replace all occurrences of '/'
with '\' in the arg string (or the string of concern) and then the user of
your program can use either.  This is what I do with programs I write.
