To connect with the device boards like- Switch, Ap, etc. previously I used minicom 2.7 in my previous laptop having ubuntu16.04. there I can perform read and write both operations. But recently I buy a new laptop on top of Ubuntu18.04, install minicom 2.7.1 but in my new setup, I have only read access not able to write anything on that board. So I am looking forward to the alternate for minicom. I have tried almost everything but it's not working for me write operations must be there on board. So if anyone has any recommendations for this or have an alternate solution for the same.
NOTE: I have tried this in both systems (16.04 and 18.04). with same USB-uart combination for 16.04 working perfectly fine but for 18.04, it is not(only have read access).
