Serial driver help

Serial driver help

[Navin Boppuri]

Hello,

Can someone tell me where I can find some documentation on how to write a
serial driver in linux using the serial.h and tty data structures? I am
using MAX3100 uart connected to the SPI controller. The SPI driver is fine
works just fine. I do see that uart.c is written for uarts connected on SMC
and SCC. All I need to do is to port it for SPI.

Thank you,
Navin Boppuri

Navin,

Check out http://www.qslinux.org/docs/snmc/serial/index.html, as it may have
the info that you need.

Hello Daris,

Thank you for the link. But all I see there is docs on how to talk to serial
ports. I need some linux data structures info. How is serial.c organized?
How can I port a new uart to serial.c ? etc. etc. Do you know of some place
I can find this?

Thank you,
Navin Boppuri

Navin,

Outside of the O'Reilly book "Linux Device Drivers" I don't know if a good
tutorial on writing serial device drivers.  If you come across one I'd be very
interested :-).


Good luck,
