They're documented. in the ms-dos 3.x documentation, by version 6 the three
unix-like options had all been dropped by microsoft. (they're not even
undocumented features any more)

IIRC DRDOS still supports some of them.

the three freature I refer to are:

 enforced \dev\ prefix for devices
     \dev\com1, \dev\nul, \dev\con,  etc.. with the un-prefixed names
referring to ordinary disk files.  (the \dev\ prefix can still be used)
join
     which behaves like mount  "join a: \mnt\floppy"
switchchar
     which lets you use "/" in place of "\" on the command-line
     and "-" in place of "/"    "dir -w c:/dos"
     the dos (and windows) kernel still supports using / in place of \ in  
  filenames that are not on the command-line

I think \dev\ was the first to be dropped and then switchchar and then join.

DRDOS still supports some of these features  (I forget which)
