Serial port- Linux kernel

Serial port- Linux kernel

[antonelloderosa]

I must control the serial port at kernel level, because I have to make several measurements of one-way delay between a source and a destination host, so while I set the DTR on the source host when I send the UDP packet, the destination host must be able to set by itself the RTS when it receives the packet.

I'm quite a beginner in Linux-kernel, so may you help me more?

Thanks again

Antonello

Hi Antonello,

if you're new to the kernel ( like me :o), you could take Rubini &
Corbets ``Linux Device Drivers'' book, and write a special driver for
your problem. That could be a nice task for learning the kernel.
I did something similar, programming a little parport-LED-lightshow.
Your real and my artificial problem enlightenes one in driver, module,
kernel and user-space / kernel-space relations, and is ( thus ) a fine
task to start with.

Frank

paper.
