82 TCP/IP AX3000 User's Manual
The AXEL tty server creates a ‘pipe’ between pseudo devices on the UNIX host
(/dev/ttypx) and AX3000 resources (sessions and/or auxiliary ports). This ‘pipe’
lets Unix treat the Axel sessions and auxiliary ports as local resources.
Note about pseudo-terminals: a pseudo-terminal is composed of two parts: a
master file and a slave file. UNIX supports two possible styles for naming pttys:
- one master and x slaves
(AT&T style): the master filename is /dev/ptmx
and the slave filenames are /dev/pts/xxx (where xxx is a number).
- x masters and x slaves
(Berkeley style): the master filename is
/dev/ptypxxx and the slave filenames are /dev/ttypxxx (where xxx is the
same number for master and slave).
