So we cant get multiple connections with writable .
lets say their was already writable connection and you want to connect to it then how can we do that ?
LDOM :- kill the current telnet process
#ps -ef | grep -i telnet
#kill -9 <process ID>
From then you can able to login to console as writable . However without killing the current process you can get the read access to console
start -force /SP/console
