Hi…
Are you asking about UART?
Sample… 16550 UART - Wikipedia

Hola Luis,

aqui un parte del syslog initializando la UART.

root@RUT955:~# dmesg | grep -i serial
[    0.507311]  serial   : 1110356993
[    0.524145] Serial: 8250/16550 driver, 1 ports, IRQ sharing disabled
[   16.361090] [01-serial-symlink.sh] New device ttyS0 at /devices/platform/ahb/ahb:apb/18020000.uart/tty/ttyS0 appeared!
[   16.862284] [01-serial-symlink.sh] New device ttyATH1 at /devices/platform/ahb/ahb:apb/18500000.uart/tty/ttyATH1 appeared!
[   17.093115] [01-serial-symlink.sh] Creating /dev/ttyATH1 -> /dev/rs485 symlink...

En el path dice algo de ahb. Para mi suena como usan un interface SPI<->UART?

For the english speakers:
Luis is asking how the RS232 port is connected to the CPU (which chip).

Best, DK
