Hi community

I am developing a control software in .net that is using linuxcncrsh (emcrsh) to open some programs in order.
The commands i am calling are:

hello EMC RSHUSER 1.0
set enable EMCTOO
set open file.ngc

Sometimes that works, but most of the times it spids out the following error message in the command line:

emc/task/emctask.cc 399: interp_error: A file is already open
can't open file.ngc

I found a Issue on GitHub that is describing an issue where it would call an error on two subsequent file loads. That issue seems solved.

Is there a way to call a specific function in between to work arround this issue?
Or is there a way to completely solve this?

Thanks in advice

Use the abort command.
The following session works for me
(tested on 2.8~pre):
$ telnet localhost 5007
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
hello EMC me 1.0
HELLO ACK EMCNETSVR 1.1
set enable EMCTOO
set enable EMCTOO
set echo off
set echo off
set verbose on
SET VERBOSE ACK
set estop off
SET ESTOP ACK
set machine on
SET MACHINE ACK
set home -1
SET HOME ACK
set open ../../nc_files/3D_Chips.ngc
SET OPEN ACK
-----> OK
set open ../../nc_files/spiral.ngc
SET OPEN ACK
----> emc/task/emctask.cc 405: interp_error: A file is already open
----> A file is already open

set abort
SET ABORT ACK
set open ../../nc_files/spiral.ngc
SET OPEN ACK
----> that worked
set mode auto
SET MODE ACK
set run
SET RUN ACK
