I currently have a program which listens to a port for incoming calls and when a call is recieved, the program forks off another process and connects its stdin/out/err to the file descriptor given by accept. This works fine apart from the fact that i am using a Sequent with a telnet which doesn't work properly. I wrote a mini telnet program myself, but what i don't know how to do is detect when the process tries to change the line condition (i.e. no echo) so that my telnet can set the state of its tty accordingly. I am sure that use of out-of-band data is required, does anyone have any hints as to how to do this or any small pieces of code that show how it is done?? -Mark
