Hi team,

I tried wrote TCP server program (TCP port number 9010) and submit it to system running it ready for TCP client connect, my question is how to running TCP client on my owner PC to connect mainframe TCP(9010) server program?

Regards,
HCEDS

The usual port number is 23 I believe - but you may be talking aboout something else. Did you really write the TCP program?

I have no idea what this "TCP" "server" and "client" are, though I hope they have nothing to do with TN3270. The other issue is whether port 9010 is open; a question I can't answer.

If this HCEDS fellow does not know how to program a (presumably) WINSOC program to connect on port 9010, or write a mainframe "server" to accept a connection on port 9010, there is little hope for him.

Yes, I write a small TCP/IP socket API server program on mainframe and bind it on port 9010.
