TVT DVR - RS232 debug CTRL+C command

[shoties 0]

I want to rebuild firmware for TVT DVR 2316ME.

 

Im using UARTO debug rs-232 connection.

Connection of COM settings seems to be fine:

Bits: 115200 / 8 / none / 1 / none

 

While reading log i can't hit break command - CTRL + C to abort. Tried in other terminals like putty etc. and other PC's. The effect is the same - system is starting continuously.

 

Any tips ?

 

Example log:

Out: serial
