Telnet Client with MicroChip TCP/IP stack?
PostPosted: Sun Jun 04, 2006 9:21 pm     Reply with quote
Using the CCS port of the MicroChip TCP/IP stack I am able to act as a Telnet host and I can send TCP or UDP packets without a problem. However if I try to "telnet" to a PC host (running Hyperterminal waiting for a TCP/IP connect) I see the connect and disconnect but the TCP data I send in the middle never shows up on the Hyperterminal. A protocol analyizer shows the TCP packet with the data arriving at the PC but I must not be following the TCP handshake properly.

Does anybody have a code fragment or suggestions that they would like to share?

Thanks,
Ron

The first thing I would do is try another telnet client or reboot the PC. Hyperterminal is very buggy.

hello

I want to connect tcp server from port 5000
I wrote this code but not working why?subnetmask and gateway setting is ok.

Code:
TCP_SOCKET ConnectToServer(IP_ADDR *IPAddr, int16 DestPort)
{
 
   NODE_INFO remoteNode;

   remoteNode.MACAddr.v[0]=0x00;
   remoteNode.MACAddr.v[1]=0x17;
   remoteNode.MACAddr.v[2]=0x31;
   remoteNode.MACAddr.v[3]=0x2E;
   remoteNode.MACAddr.v[4]=0x26;
   remoteNode.MACAddr.v[5]=0xD5;

   remoteNode.IPAddr = *IPAddr;
   
   return TCPConnect(&remoteNode,DestPort);

}
