Для получения результата был сделан шнурок, подключаемый с одной стороны к колодке J16 на baseboard, с другой стороны к USB-Serial хвосту. В Линухе появляется устройство:

ofei@Korogodin-Notebook:~$ ls /dev/ttyUSB0
/dev/ttyUSB0

Скорость по-умолчанию - 115200 бит/с.

Update 26.04 20:54

Линия TX тоже функционирует нормально (правда почему-то только в связке с matlab или gtkterm):
