One may think of them as two serial devices linked by a null-modem cable. Being based on devices the number of simultanous instances of this class is (globally) limited by the number of those device pairs, which is 256. Another technic are UNIX 98 PTY's. These are supported also, and prefered over the (obsolete) predecessor.
