The driver which to Eriks Rugelis is referring (and the only PTY driver I know of to appear on the DECUS tapes) was originally written by Gary Grebus (it's first incarnation on the SIG tapes). I took Gary's original, converted it to VMS V4, and made other changes and resubmitted to the Spring '85 (New Orleans) tape. This driver is distinguishable by the fact that it is called PTYDRIVER and consists of only one template device, PTY0:. The CMU driver is broken into two devices, called PYDRIVER and PTDRIVER, or PYDRIVER and PZDRIVER (since DEC usurped the PT naming convention) and a system using it will have both a PYA0: and a PTA0: (or PZA0:) template device. I have worked on both pseudo-terminal drivers, but have only ever put PTYDRIVER on a DECUS tape. There is absolutely no connection between PTYDRIVER and the CMU driver -- neither Gary nor myself had a copy of the CMU driver at the time we did PTYDRIVER. The courtesy that was dropped was in not mentioning Gary as the original author of PTYDRIVER. /Kevin Carosso engvax!kvc @ csvax.caltech.edu Hughes Aircraft Co.
