how to disable tx from BB when i just want it to receive data from a receiver?


i have been having these issues lately. i am using a minicom on HOST connected to BB and BB is connected via serial-usb to a GPS receiver.

when i do a cat /dev/ttyUSB on minicom…the BB starts transmitting something to the receiver instead of just receiving data. how can i disable the BB from transmitting?

Someone please help!!!
