Removing Watchdog in terminal emulation program

I am unable to find the answer to the question in any of the manuals. I am communicating with the AX1500 via an RS232 and a terminal emulation program. On startup it enters the RC mode, and I carriage return 10 times to put it into RS232 Watchdog. I would like to remove the Watchdog. Is there a way to do this in the terminal emulation program? When I use the software, I put it into RS232 and remove Watchdog, but when I try to save it, I get errors. I would prefer not to use this program, I would like a command to remove watchdog in the terminal.

When entering RS232 from the RC mode and sending 10xCR's, the watchdog is always on and cannot be disabled.
