又一个我自己写的tcp/ip的代码，直接编译后烧录到mcs51中即可运行。（没有做mbuf的）部分代码是用mcs51的汇编写的，其它全部用C写的-also one I wrote it myself tcp / ip code, compiled directly onto mcs51 which can run. (Do not Mbuf) part of the code is compiled with the mcs51 made in all other written in C

tcp通信，自己写的有bug,xiazaihou qingzixingchaxue-tcp ,by myself ,maybe there are some BUG

TCP通信,简单易行，在VB上使用的，已验证过正确性了，求支持(tcp communicationused in vb,has been used by myself.)
