No, I did not. The source archive contains everything that is necessary to build picodosl.lib (have you tried? just type 'wmake'). picotcpl.lib, on the other hand, is the "stock" version of picoTCP. I didn't include its source code on purpose, since that's out of scope of my project. picoTCP's source code can be fetched from www.picotcp.com, or their github profile. It does require some small patches however - some of them have been already integrated into the upstream picoTCP, but these that were not, are all present in the source package (inside the 'picotcp' directory). > b) the only provided example program PING.EXE is HUGE (120K/63K when > compressed) when compared to mTCP ping.exe (40K/28K compressed) I noticed that picoTCP have a tendency to link almost all its code, which indeed results in bigger-than-expected binaries. The good point is that binaries don't grow if you use more features. But yes, for just ICMP, it might look odd to end with 60K. Note, that ping is not the only example program - there is a socket-based program (very basic http downloader) in the source archive called "socktest.c" that is probably a better example to look at. Its binary size is 110K/57K upxed. Second note: yes, picoTCP might end up statistically slightly bigger than mTCP, but on the other hand it's far from what we end up using Watt32 :) (ping.exe of almost 2M!) > what exactly is the advantage of 'pico'TCP? It's open-source and maintained. And it's used in a much broader scope than just DOS, which is a big advantage considering the size of the DOS community. Oh, there's also this IPv6 thing :) (beware however, that the current version of ptcp4dos doesn't include ipv6 yet) Mateusz > am 19.
