I did it all the time. For terminal stuff, it was much easier than trying 
to work through the cumbersome indirection layer imposed by RMS.

Remember that POSIX has no “RMS” layer. A VMS “channel” might be 
considered equivalent to a POSIX “file descriptor”, except that “files” 
are just streams of bytes, and “file descriptor” refers equally well to 
data on persistent storage, or pipes or sockets. On Linux, it even has 
other uses to do with certain kernel control/notification APIs, not for 
regular data transfer at all.
