UART Headers

The conga-IA5 provides two UART headers (X24, X25) via a Super IO (NCT6102D). The UART ports can be used under Windows 10 and Linux
without a special driver. UART header X24 (COM 0) fully supports RS-232. UART header X25 (COM 1) supports RS232 (Rx and Tx only), RS422
and RS485. Optionally, UART header X25 can be used for ccTalk instead.
