[Simh] Basic questions

I agree that (see below) is a good, detailed reference.  I found this one to good too, but Lennert is creating a Cluster and installing DECNet, both non-novice operations.  So the reader has to kind of edit the procedure:

https://vanalboom.org/node/18

A few comments are in order:

1. HP's license package includes a UCX, not TCP license.  I doubt a novice would recognize that the UCX license works fine for TCP.

2. Interfacing to Ethernet is a bag of worms.  Lennert's discussion is dated because Jordi points out that SIMH 3.9 has added functionality.  See 

http://ancientbits.blogspot.com.es/2012/06/simh-39-using-vde-for-fun-and.html

But his example doesn't work either.  In particular I get the following error:

david at Thinkpad:~$ sudo brctl addbr br0
david at Thinkpad:~$ sudo ifconfig tap0 up
tap0: ERROR while getting interface flags: No such device
david at Thinkpad:~$ 

3. VMS has several editors available.  If the user isn't careful, editing files could be very frustrating.  The following works:

$ SET TERMINAL /DEVICE=VT100
$ EDIT MODPARAMS.DAT

The following doesn't

$ SET TERMINAL /DEVICE=VT200
$ EDIT MODPARAMS.DAT

To see which terminal-type SIMH defined, use the command:

$ SHOW TERMINAL

To add to the confusion, the following works in either case (because it's a different editor)

$ EDIT/EDT MODPARAMS.DAT

Well, I'm belaboring the point.  There are several books available that describe basic VMS commands, keyboarding, functionality etc.:

Duffy, Getting Started with OpenVMS
Holmay, The OpenVMS User's Guide
Rice et al, Introduction to OpenVMS

So, I have SIMH/VAX running and I'm pleased with all of your fine comments, suggestions and assistance.   Thank you very much!

David.

I know very little about VMS, but I found this to be a great guide:
