• (TJ, with much information provided by H. Peter Anvin) Yes, but only if you have a kernel and libc which support them, and if your applications are written and compiled to use them. They will be supported by Linux 2.2 and glibc 2.1. This is in Documentation/Changes that comes with the kernel sources. There is also the new standalone libpt by Duncan Simpson which implements the Unix98 PTY API independently of libc (check the Incoming directory on metalab.unc.edu/Linux and mirrors). You still need to have your apps compiled to use this API, of course.
