Pseudo-Terminals (ptys) are a type of interprocess communication with a master
|
|
and a slave end. One program (in our case nullmodem) opens the master sides of
|
|
connections and therefore provides connectible slave sides of connections.
|
|
If nullmodem receives some data on one of these connections it retransmits them
|
|
on all other connections. It can be seen as a network with star-type wiring.
|
|
Because the names of the slave side ptys are dynamic, nullmodem creates
|
|
symbolic links to filenames of your choice.
|
|
e.g. the command nullmodem /tmp/loop0 /tmp/loop1 /tmp/loop2
|
|
creates a pty-network with 3 slave sides linked to the names /tmp/loop0,
|
|
/tmp/loop1 and /tmp/loop2.
|
|
If you close a slave side connection nullmodem will detect this and provide
|
|
a new stub to connect to and update the symbolic link.
