Kamil reported that his Samsung Artik 710, so another one for the collection. The only interesting Linux kernel hits are under: so it seems to be strictly linked to the PL011: which is a UART controller licensed by ARM, which I think is the dominating implementation. It seem that AMA is a shortened form of AMBA? But why would they shorten a 4 character acronym?!
#PHP SERIAL PORT COMMUNICATION LINUX KERNEL SERIAL#
I get the splash screen appearing, all the usual debugging information loading serial ports etc. I think I would be able to connect my desktop with a serial port to my RPI with that interface: raspberry pi 4 eglfs 12) or linux-rasp-pi-g++ (Qt 5. Haven't run into that for real hardware, will post pics when I do. Karachi The Linux kernel provides the serialrs485 structure (see 1) to. I also get it when I connect the GPIOs of my Raspberry Pi to my laptop to get a shell on a Raspberry Pi without a screen!Īnd another more integrated RPI connector version of the above: You can communicate with any device or instrument that has a serial interface.

Be sure to read the list of supported ioctls above to figure out what will work with the driver. If you haven't done serial programming on linux before read the LDP Serial Progarmming Howto. What you get on host when using something like: The linux usb web site is the place to go for anything to do with usb and linux. I think those cables cannot be too long or else the signal is lost though, and you can't do as much without the TCP/IP addressing/packet mechanisms. So this is a bit like SSH and can be seen as an early form of networking. From Linux computer 1 you would run: screen /dev/ttyS0 115200Īnd then computer 2 would reply with the login prompt, and then you can log in from computer 1 into computer 2. You also get it with qemu -device isa-serial.įor example could hook up two desktops with one of those cables, and communicate directly between them to get a shell on the remote desktop from your own. This port is not present on most laptops or small devboards, but is still present on many desktops, and is very convenient for OS developers as mentioned at: High reliable SUN2410 16C950 compatible native PCI Express UART controller on-board.

What you get on the host when you connect to target with this: Expands four RS-232 serial ports with communication speeds up to 115.2Kbps.
