(only sysop, not possible via air connect)
Syntax: CONN(ECT) [interface:<hw-addr>] <call> <digi>

With this command it's possible to connect from sysop console to others. This
possibility is not very comfortable but working. To disconnect use :D command.
If you want to connect via Linux AX25 kernel you have to add interface and
hardware address (call of interface).

Example: connect ax25:db0aab-13 oe3dzw db0aab
