[Simh] Emul. DL-lines over Telnet for PDP11, but all char's are converted Upper Case

[Göran Åhling]

In running SIMH PDP11, with RSX11M+ 4.6, attaching DL-lines using 
TCP/IP-telnet, I run into a problem of "character conversion".
Whatever I write is converted into UpperCase. This seems to be according 
to the SIMH manual, that states 4 different modes available, with UC the 
default.

My problem is that the manual doesn´t state how to change mode, just 
that 4 different modes exist.

In SIMH i can do SHOW TTIX0:, SHOW TTIX1: etc, and I can do SET 
TTIX0:..., but when I try SET TTIX1:, the emulator replies with "DEVICE 
NOT PRESENT" (or anything close to that, I'm not sitting next to the 
system right now...) (Is this really a bug or a feature I have not fully 
understod ??)

I have made sure the OS (RSX) is set /LOWERCASE, which does the job on 
true HW.

I'm running the "latest" binaries for Win... available on a machiene 
running a fully updated Win XP.
I have tried a couple of different terminal emulators (Putty is one of 
them) with the same problem, and running the same emulators towards 
other systems (for example VMS with TCP/IP) works fine. Working this 
target system using LAT from a emulated terminal connected to a VAX also 
works fine, thus I conclude the problem arises from SIMH, not from the 
terminal programs and not from the RSX.

The reasson for running DL's, as opposed to DHQ's or DZ's,  is that this 
SIMH has a true clone of a running, working system with 11/93-cpu, where 
the DL's are (on the CPU board). I don´t want the "clone" to be 
differently SYSGEN'ed than the true HW version...

Any suggestion apprecieated!
