RE: time to hack and decompile the agrmodemlib.o to document its secretsI'm not erudite in C or COMM code. But a deep documentation may notbe necessary The ltmodem code for the earlier Digital Signal Processing (DSP)chipset modems was a predecessor of the agrsm code. If you look atthe agrsm LICENSE etc, Agere/LSI programmer Soumyendu Sarkar clearlyused the ltmodem base as much as possbile.Likely what is mostly new is that the DSP functions are now sent tothe CPU, rather than to a DSP chip on the modem card. So a guess is that if someone erudite enough following the examples ofthe slmodem or martian code packages, it would be a good start to thecomparable agrsm code package. While I suggested this to Alexei, of course, he is likely overworkedenough with teaching, making a living etc, MarvSOn Tue, Jul 29, 2008 at 10:33 AM, Bjorn Wielens <uniacke1@xxxxxxxx> wrote:> Hi Emmanuel,> Changed the subject line, otherwise someone might> google and get a thread that is not really useful...> :)>> You have a very good point regarding what GNU/Linux> is... and assuming the licence of the agrsm software> is similar to that of Lucent's LTmodem software.
