Regarding Pseudo tty, Pseudo terminals ?
 

Hello there,
Does anyone have any info on how pseudo tty works? i have read online and saw the code which involves opening master slave devices and the data is transfered from/to them...i want to know if i can use that in the following situation.

the thing is that when sms arrives a device in linux called /dev/mux is ready to be read... tapisrv reads that device and handles the incomming sms. is it possible to open another dummy dev like /dev/dummyMux and upon invokation of /dev/mux the data is read from it before tapisrv gets it ?

any advice would be appreciated..

thanks alot,
Mudassar
