Well, you are right - the kernel support for winmodem is good if one wants to use ppp et al. On the other hand, it seems that having support for some specialised protocol can produce a lot of overhead in some cases. For example, I once owned very simple Zoltrix, that could do error correction and compression only via the software driver (available only for windows, of course). So, it was almost unusable until I started doing ppp on it. The ppp driver took care about errors and compression - now, with the same futures implemented in lower layers it would be a waste of cpu. So, if you want to do kernel support for winmodem, it would be probably good to remember about ppp. Of course, if you choose to implement full support and emulate v34 or anything else, you would be able to turn the compression (and || or) error correction off either on the emulated 'modem' or in ppp options. Anyway, I think you could have a look at www.linmodems.org. It seems to contain some interesting things. bye T. - -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.
