+Normally, pppd requires a terminal device.  With this option, pppd
+will allocate itself a pseudo-tty master/slave pair and use the slave
+as its terminal device.  Pppd will create a child process to act as a
+`character shunt' to transfer characters between the pseudo-tty master
+and its standard input and output.  Thus pppd will transmit characters
+on its standard output and receive characters on its standard input
+even if they are not terminal devices.  This option increases the
+latency and CPU overhead of transferring data over the ppp interface
+as all of the characters sent and received must flow through the
+character shunt process.  An explicit device name may not be given if
