I got Vocore2 Ultimate and I'd like to use TTL but it seems that pins TXD2, RXD2 and GND are already taken by the dock - there are no empty holes but very short heads in their place. Should I just get a pin header and solder it onto these tiny heads in order to use TTL or it's just not possible to use TTL with a dock? I already have some jumper cables I used with other boards.
I attach a photo of headers I am talking about.

On the ultimate the USB/UART converter is built in just connect to the mico USB connector.
On linux the VoCore2 will be /dev/ttyUSBx, x is set automatically but will likely be the highest numbered one.
I use picocom on Linux, kermit works too.
On Windows you will need to install PuTTY and make a serial connection to whatever COM port Windows decided to put the VoCore2 on.
