Nick de Smith Applied Telematics Group 7 Vale Avenue Tunbridge Wells Kent TN1 1DJ England +44 892 511000 PSI%234213300154::NICK This directory contains my version of a totally re-written pseudo terminal driver, that is compatable with the old PT/PY drivers. This version should be much easier to support. The original author of PYDRIVER/PTDRIVER (or whatever) was Dale Moore (in November 1982, I think). Since then, many people have modified the drivers, including: Dale Moore (again!) D. Kashtan on several occasions Mark London Doug Davis Kevin Carosso for many and major changes and probably many others who should be acknowledged, but whose names are not on the original listings. I took the liberty of re-writing it simply because I couldn't understand what was happing any more. In addition, subtle bugs were imbedded in the structure, and there was much redundant data and code. It was time for a re-write and re-structure. It is not my intention to detract in any way from the original authors of the pseudo terminal drivers, who have produced a wonderful tool. I will endevour to keep this version functionally compatable with the original PY/TW drivers. I have used the same names for compatability. My versions do not yet have the SENSEMODE/SETMODE/flow control functionality of the new versions of Kevin Carosso's drivers, but will do in the next release. My versions are directly compatable with the V4.x drivers. When VMS V5 can along, and terminal port drivers were documented (sort of) I completed the re-write and tried to make sure that all comments are accurate and not misleading. In addition, hooks have been added to make addition of enhancements much easier. In particular, the QC$STARTIO routine has been generalised to include SETMODE support. DIRECT I/O was added because we have a network server that may run 100+ simultaneous sessions, and I wanted to optimise data transfer. To use this feature, use LOGICAL or PHYSICAL I/O operations. Any comments gratefully received (see PLANS.TXT first). Nick ps. BACK*.* is a virtual terminal program. See BACKUP.COM for how to build it, and LOGIN.COM for an explanation of what we use it for, It can log to files. BACKUP.C is similar to the old PTY.PAS/PHOTO.C. It uses the drivers.
