[Simh] pdp10 mux and clock issue?

2019-02-25 Thread Quentin North 
Hi

Im using the pdp10 emulator and running tops10 7.0.4 and Im seeing a couple of 
issues:

- Intermittently a terminal session will issue a TOPS-10 command (say R SUBFIL) 
and the mux will echo the characters but then the session will not do any 
output from the system until I go to the CTY and get it to output some 
characters in user mode (ie outside of OPR console) and then the output will be 
released on the user terminal. Input continues to be echoed but there is no 
output until I do something on the other terminal. This seems to happen more on 
simhv3.9-0 vs simhv4.0-0 but occurs on both. Im not sure if this is a mux 
problem or an execution problem.

- The clock seems to drift slowly backwards. Over the space of a day it 
appeared to loose about 5-10 mins.

Does anyone have any ideas of what may be the issue or what further diagnostics 
I could do when the problem, especially the paused output problem, occurs?

The setup is using CPU IDLE, show config is:

Hi Mark

Now using latest simh, I am experiencing the same problem with DZ, and if 
anything it might be worse in the sense that character output seems very slow 
even when working as expected. Config and ver as follows, telnet client is a

Hi Quentin,

Please try using the latest code from https://github.com/simh/simh (available 
as a zip from https://github.com/simh/simh/archive/master.zip) and confirm if 
you are still seeing the problems.  Also, please identify what telnet client 
you are using to connected to the DZ ports.

Thanks.
