How do I enable script debug mode on the player?

I can't get this to work using a XD1030. The LED doesn't flash when holding the SVC-button and I get nothing via RS 232 from it. I have tried using putty and Realterm. Nothing works. I have also tried enableding SSH. With the only result that the Error-LED flashes ... The only thing I got to work is telnet using a script from the github.

Same problem with 4K1042

Edit: Sending abort signal(CTRL-C) doesn't do anything and I am connected through SSH. I was able to get it working earlier but after I factory resetted the player it does not work anymore.

Edit2: So after lot of fussing around. I was able to get it working. In case someone else wants to it, here are the steps.

Step 1: get ssh enable plugin from brighsign github page

Step 2: Enable SSH

Step 3: SSH into the player.

Step 4: Press the SVC button on the player Once(Don't need to hold it).

step 5: Enter "Script debug on" on the prompt.

I have followed the steps and reached the prompt, however, the command "Script" was not found, 
and when trying lower case, it has failed, I am using the latest firmware on the XT1143.
Any ideas?

What does the prompt say? does it say brightsign or brightscript debugger or just a #?

it says BrightSign,

if I enter "script" i see the following

BrightSign> script
BrightScript Micro Debugger.
Enter any BrightScript statement, debug commands, or HELP.

Current Function:
001: stop
STOP (runtime error &hf7) in (1)

001: stop
Backtrace:
Function main() As
file/line: (1)

Local Variables:

BrightScript Debugger> 

EDIT: I exited script and typed it in all lowercase and it seems to work now,
thanks for the quick reply

Tried the instructions here:

SVC does not make the Err light blink. Cannot enable this at all.
