[Simh] Simh Digest, Vol 167, Issue 30

[Mark Pizzolato]

Hi Kurt,

This is a duplicate of a recently reported problem with host physical serial port connections through the DZ device on the VAX simulator.  Details at: https://github.com/simh/simh/issues/504

I haven’t had time to setup the environment to test this so I can track down the underlying problem.

Meanwhile, you can connect the physical terminal to the VAX simulator’s console port with:
     sim> SET CONSOLE SERIAL=ser0;9600-8n1
or equivalently on your system:
     sim> SET CONSOLE SERIAL=/dev/ttyUSB0;9600-8n1

The failure of your command:
    sim> attach ttix line=0,connect=/dev/ttyUSB0;1200-7n1
    Non-existent device

Is pilot error on your part.  There is no TTIX device in the VAX simulator and the error message correctly reports that.  That command might work on the PDP8 simulator which does have a TTIX device…

My sincere apologies to the group for posting a complete thread with my question below.

I wanted to clarify.  I can connect the terminal to the Raspberry Pi via Raspian with no problem.  I would like to connect the terminal as a serial device within Simh.

I am having a devil of a time hooking a physical VT220 into my Raspberry PI
Simh VAX.  Everything is setup and working beautifully.  I can telnet from
another computer with no trouble and get a vax login.

I have a ttyusb0 connection.  I can echo text to the terminal with no
problem.

I can configure Raspian to divert the console to the terminal with no
problem.  But, I can't telnet to the vax from the Raspberry PI operating
system.  I can telnet from another PC, but not from within the Raspberry
Pi.  So, that doesn't give me the Vax login on the terminal.

So, I tried to create a serial connection to the ttyUSB0 using various
means.
Method 1) attach ttix line=0,connect=/dev/ttyUSB0;1200-7n1 - This results
in an error that says non-existent device.
Method 2) attach dz line=0,connect=/dev/ttyUSB0;9600-8n1 - This seemed to
run successfully, but showed nothing on the terminal after a reboot.

Is there a way to connect a physical serial terminal via /dev/ttyUSB0 using
SIMh Microvax 3900 simulator?

Thanks for any advice.

Kurt
