I issue the following command:

/usr/sbin/asterisk -rx “rpt showvars 1100”

asterisk returns:

^[[23;1R  
^[[23;1R  
Variable listing for node 1100:  
RPT\_TXKEYED=0  
RPT\_NUMLINKS=2  
RPT\_LINKS=2,T1102,T1101  
RPT\_NUMALINKS=2  
RPT\_ALINKS=2,1102TU,1101TU  
RPT\_ETXKEYED=0  
RPT\_RXKEYED=0  
RPT\_AUTOPATCHUP=0  
– 8 variables

Can anyone tell me what those 2 first lines of (assumed) control characters are all about?

Not for me. Must be a TERM= thing.

```auto
asterisk -rx "rpt showvars 25330"
Variable listing for node 25330:
   RPT_TXKEYED=0
   RPT_ETXKEYED=0
   RPT_NUMLINKS=1
   RPT_LINKS=1,T2530
   RPT_NUMALINKS=1
   RPT_ALINKS=1,2530TU
   RPT_AUTOPATCHUP=0
   RPT_RXKEYED=0
    -- 8 variables

My first thought is corruption… restart.  
After that, I would ask if you are declaring vars under event management.

The more I thought about that, the more I’m thinking it is a few chars like right arrow or something like that.  
Have you edited your source code any ?

Nope, no playing with the source - this is the latest beta. Also, I have not declared any variables.

I’ll poke at one more question…  
Have you declared global vars in extensions.conf ?  
If so, mask them out ( ; ) restart and look again.

Only NODE and HOMENPA

But I will comment them out, restart and see what happens

Ken, did you ever resolve this. I am curious what you found.
