this looks fine

this will not work. as per l2control(8) man page

"
The l2control utility connects to the local device with the specified
BD_ADDR and attempts to send the specified command.
"

i.e. l2control(8) will display _local_ l2cap channels (basically l2cap
connections). you dont have any l2cap channels (i.e. connections).

i'm guessing you want to see the services offered on your t610 phone.
you need to use sdpcontrol(8) for this.

yes, this will tell you service names and service parameters

well, it could not open /dev/ptyp6? is it busy? did you try different terminal?

l2control(8) is not an issue you. rfcomm_sppd(1) had problem with
opening master pty.
