Error to debug my shop!

[jojo@buchonline.net]

Hi list,

i have set the option "-d" to debug my shop. But i get a error message
like

Debugged program terminated.  Use q to quit or R to restart,
   use O inhibit_exit to avoid stopping after program termination,
   h q, h R or h O to get additional info.
 ######### Forked, but do not know how to change a TTY. #########
   Define $DB::fork_TTY
        - or a function DB::get_fork_TTY() which will set $DB::fork_TTY.
   The value of $DB::fork_TTY should be the name of TTY to use.
   On UNIX-like systems one can get the name of a TTY for the given window
   by typing tty, and disconnect the shell from TTY by sleep 1000000.
   DB<2>

server:/home/mvend[mvend]# tty
/dev/ttyp2
server:/home/mvend[mvend]# 

I have no clue, how to do! Can somone point me the right way, how can i
use the option "-d" and set the value of źDB::fork_TTY?

I will be very glad, to get help. I want to watch the value of mv_case
for example!

Thanks! 

Joachim
