I would like to use a pty to let a process emulate a device. However, it looks to me like the pty interface doesn't really provide enough control and status on the master side. For example, I don't see how to: * send a HUP to the slave side process by operating on the master (to emulate a device hangup) * cause the slave side process to block on open (for example to simulate waiting for DCD) * detect the slave side open not just its first write. * detect device specific slave side ioctls and reply to them from the master side. Can any of this been done on the existing BSD or Sun pty driver? Has anyone done a more general pty streams module that does more of this. -- Ken Mandelberg | km@mathcs.emory.edu PREFERRED Emory University | {rutgers,gatech}!emory!km UUCP Dept of Math and CS | km@emory.bitnet NON-DOMAIN BITNET Atlanta, GA 30322 | Phone: (404) 727-7963
