I do not know anything about minicom... But I try to change the device to /dev/ttyUSB1 or /dev/ttyUSB2 and the result as follow " # /usr/local/sbin/bearerbox /etc/kannel.conf 2009-03-21 08:19:52 [0] INFO: Debug_lvl = -1, log_file = <none>, log_lvl = 0 2009-03-21 08:19:52 [0] WARNING: DLR: using default 'internal' for storage type. 2009-03-21 08:19:52 [0] DEBUG: Kannel bearerbox version `1.2.0'.
