We currently have an application which we wrote that uses NETBIOS calls to establish peer-to-peer communication between 2 (or more) PCs. Recently we have tried both FTP's PC/TCP and Wollongongs WIN/TCP running their NETBIOS over TCP/IP packages without success. I have a few questions and observations. 1. For simple NETBIOS applications, the packages seem to work but our application is very often sending data in both directions at the same time. For standard NETBIOS LANs, this works fine, but over TCP/IP we get a connection closed message after just a few packets in each direction. (Sometimes everything just hangs...) Is this a implementation problem or is it a more basic restriction in TCP/IP protocols? Would it be better to access TCP/IP directly, rather than using the NETBIOS interface? If anyone is interested, I have a (fairly) simple test program that starts up a NETBIOS session between two systems and then each system starts sending files to the other node (simultaneously). 2. We are interested in converting our application to use TCP/IP directly. Is there a standard interface, that provides reliable flow-controlled transmission? How about an application developer's toolkit? Would it have to be vendor specific? Thanks. Chris Toulson Bell Northern Research Montreal, Canada chris@inrs-telecom.uquebec.ca
