From: Mike Ciaraldi <ciaraldi> Can anyone give me some help on the TSX-Plus timesharing system which runs with RT-11? Specifically, I am helping someone expand his system. He now has a PDP-11/44 running RT-11 version 4.0 and TSX-Plus. He wants to add another terminal. He already has the serial port hardware, he just needs to adjust the software. He presently has 2 DLV11-J 4-port serial boards. 4 ports are used for terminals, two are for the printers. The other two are not being used. He wants to set one up for a modem (incoming). So, the question is... Does he hacve to re-do his RT-11 SYSGEN? Or does he have to INSTALL another terminal handler? Or does he just re-do TSGEN? I ran the RESORC command and it says that RT-11 has no multi-terminal support, but looking in the SYCND.MAC file seems to indicate it was requested. Does TSX totally override what RT-11 set up? As you can see, I don't know a lot about how this system was set up (someone did it for them 3 years ago and it hasn't changed since). I read through the RT-11 SYSGEN manual and the TSX manual and there are an awful lot of things they leave out, such as EXACT definitions of some technical terms. Thanks in advance for any help you can give. Mike Ciaraldi seismo!rochester!ciaraldi

Last I remembered, TSX was configured independently from RT-11, only retaining compatibility with RT-11 programs. Do another TSGEN. Terminal handlers are shared, if I remember correctly. You just have to let TSX know the lines are there. Ken -- UUCP: ..!{allegra,decvax,seismo}!rochester!ken ARPA: ken@rochester.arpa USnail: Dept. of Comp. Sci., U. of Rochester, NY 14627. Voice: Ken!

Reconfiguration of TSX-Plus to change the number or type of time- sharing lines is accomplished entirely by editing the TSGEN.MAC file and then rebuilding TSX-Plus. In fact, TSX-Plus requires a stripped- down RT-11 single-job system, and attempts to build a more complex version of RT-11 will probably lead TSX to tell you that it does not have enough memory to start. The only requirement of importance is that RT-11 recognize all loadable device drivers specified for TSX: terminals are not handled through a loadable driver by TSX. 2. Changing the number and type of lines is well described in the TSX-Plus System Manager`s Guide. Basically, you need to change the declared number of lines, then add a LINDEF statement for each new line. If a new multiplexer is to be added, a new MUXDEF will be needed as well as a LINDEF. The TSGEN.MAC file adequately describes the flags that determine whether a line is remote or local, and so forth. 3. S&H (the people who wrote TSX) are generally competent and helpful. Call them if you still have problems. 4. TSX-Plus is an extremely nice system for a small multi-user PDP11 system. Apart from anything else, informal tests suggest that it is a great deal more efficient than either RSX-11 (gak) or 2.9BSD Unix. I have used it for three years, and recommend it highly. 5. There are hordes of trademarks here. I am in now way associated with the owners of any of them except as a frequently-dissatisfied customer. I am more satisfied with TSX than with most other things in the computer software world.

All he needs to do is to modify TSGEN.MAC (between the "======"'s that mark the user-configurable parameters. RT-11 multiterminal support is NOT required. If he has any difficulty bringing TSX+ up after the regeneration, he might need to reduce the size of RT-11 by regenerating the RT-11 baseline or single job monitor, but that's unlikely. Also, if the system seems to crash frequently with a "no free fork blocks" message, he may need to increase NUMFRK (near the beginning of TSGEN.MAC). With the RT-11 baseline monitor, 14 lines running on two DZ-11 multiplexors, and NUMFRK = 170, we have few problems on an 11/24. -- John Miller (ecsvax!phco) Dept. of Pharmacology, Univ. of N.C.-Chapel Hill Chapel Hill, NC 27514 (919) 966-4628

I have successfully redone the TSX system generation (as it says in the manul, it really DOES take 15-30 minutes once you know what you want to do), and everything is working well. Thanks again. Stay tuned to this newsgroup for more of my troubles with this system... Mike
