[Simh] hp2100 IPLI and IPLO devices

[Ken Cornetet]

As Emily Litella would say: "Never Mind". By some amazing stroke of
luck, the DVM72 manual is on HP's web site. A quick perusal shows that a
certain bit must be set in the IO request to indicate a binary transfer.
It also shows a few different ways to do IO via the device.

 

Setting this bit at least gives me some data to the telnet session.
Woot!

I've been trying to use the IPLI and IPLO devices under RTE-6 with no
luck so far ( I know these devices are intended for 2000 timeshare
basic, but I was hoping I could use them under RTE as well).

 

All writes to either device just complete immediately, and reads
complete immediately with no data.

 

If I do the following commands

 

set console debug=stdout

set IPLI enable

set IPLI dev=53

set IPLO dev=54

set IPLI debug

set IPLO debug

attach -l IPLI 4000 

 

And attach with telnet (telnet 127.0.0.1 4000) I can see socket activity
via the debug information:

 

>>IPLI svc: Socket read = 006412, status = 2

 

But I don't see any device IO activity debug messages

 

If I try putting the cards in DIAG mode

 

set console debug=stdout

set IPLI enable

set IPLI dev=53

set IPLO dev=54

set IPLI debug

set IPLO debug

set IPLI DIAG

 

I don't see any debug message, nor does RTE see any data if I write to
one device and try to read from the other.

 

I'm using RTE driver DVM72 which is the general purpose driver for the
12566A card.

 

Any suggestions other than "Don't do that"? (Doc, it hurts when I do
this...)
