In fact, most commercial TCP/IP packages for DOS can be purchased with an Applications Programming Interface of some sort. Our PC/TCP, Sun's PC/NFS, Excelan's EXOS 8051, and NRC's all have libraries that emulate Berkeley sockets, for Microsoft C. I don't know details of Bridge's offering. I think each product supports all memory models, but I don't think anyone is shipping code for 5.0 or 5.1 yet. In addition, our Developer's Kit comes with libraries that allow access to our native interface (interrupt-based, with fairly rich asynchronous facilities - our NETBIOS was written with it), as well as high-level libraries providing callable FTP, Telnet and Rlogin. Regarding the original question (TCP/IP for MVS), I believe that ACC offers one, in addition to Spartacus. Both provide FTP, Telnet (including TN3270) and SMTP. Both have UCLA MVS ancestry. Both need hardware (a front-end) sold by the vendor to actually provide the network connection. Writing your own FTP gateway on a PC would certainly be possible, particularly if it was batch mode, but I'd be cautious about such a project, because the development would take a while, and then there would be issues of reliability and maintenance...
