When I upload data from DPS (where my tcp implementation is) to windows (an ftp server takes the data there), the windows tcp hangs at times. It happens only at 100 MbpS. Something like 8 megabytes/S get sustained for a few seconds with several retries, then at some point the windows tcp acks only part of the last segment it could take with a window size of 0. My tcp retransmits that seg...

Various people such as make equipment so that you can remotely actuate relays/read closures & temps; all via a web server & TCP/IP. What I need is a pair of "computerless" boxes: Plus button A on master box; contact A closes on slave. Short contact C on slave, see closure on master. They talk to each other directly over TCP/IP. Has anyone ever seen such?

Hi I have a system comprised of a computer with a TCP/IP application and a gateway connected to this computer. I need to measure the delay of the gateway, by measuring the delay on the output of the gateway and the signal on the ethernet line But, the ethernet line is active all the time and I do not have a TCP/IP decoder and it is impossible to trigger on the burried TCP/IP packet. From ...

Folks, Did everything in the book. Configured it via a TCP/IP port because the SMC software will not run on Windows 7 Professional 64-bit. This direct method generally works also on machines with other OS'es. Since Windows 7 is seriously dumbed down there are zero error messages and the so-called troubleshooter finds nothing. If I print to the connected printer it all disappears somewhere ...

Can two different types of Homeplug devices be mixed ie will a couple of 85Mb Turbos conflict with a couple of 200Mb AVs? I want to use the high speed one for normal Net style activities, and use the lower speed one to pass around miscellaneous low speed serial data, not TCP/ IP or UDP. Dirk

Hi All, I want to install some real-time CCTV cameras to monitor CNC machines for tool breakage etc. I don't need to record, just view the stream and hot-foot it to the shop if things don't look right. I need to be able to feed the video (BNC-connector) to a "box" that can connect to my Vista Network (TCP/IP) with an RJ45 and an assigned IP similar to the CNC machines. Currently the C...
