Dialup Client / Server

[Brandito]

Hey. I am trying to find information on coding Dialup clients and servers in C. I've looked around on the net and haven't found any documented coding explanations.

Does anyone know of a good site or source that would talk about dialup programming in C?

It would be preferable if it was for Linux, but I windows doc's would also be welcomed.

Thanx,
Brandito

From your description, it looks like you are trying to code at a low level to mess with COM ports. Windows documentation specifically states that you must write your own proprietary driver, rather than use the comm.drv driver that comes with windows. You have no choice but to write a driver if you're messing with the NT family anyway, because you can't easily access low-level memory calls because the OS blocks it.

A sample of that driver is in Walter Oney's book 'Programming the Windows Driver Model'.
