The default configuration is 115200 8N1 with Hardware Flow Control. I usually disable Hardware Flow Control in my setting and save to the default 'df1'.

Tio

Although minicom describes itself as "friendly", it can be painful to setup and use.  As a suggestion, if you don't need send/receive abilities like xmodem, tio is much easier to use.
