Hi all, After a fair bit of googling I came across this: http://www.hw-group.com/products/hw_vsp/index_en.html It is a virtual serial port for any TCP/IP device. Very useful for testing GPRS connections, connecting to network enabled devices using serial programs etc. Plus its free and time-unlimited, unlike the TCPCom program which is typically quoted or returned via a google searc...

I noted that others were looking at and commenting on low cost solutions for TCP and related services as network controllers. One of the best solutions today is the Microchip dsPIC and PIC 24. They are not 8 bits but 16 bits and share lots of great pic features. This is what you get: - low cost hardware - support for just about all interconnect you can imagine (no firewire though) - cots...

Hi there, Anybody have experience in implementing an eCos TCP/IP stack on an ARM? Is a footprint of 200k program memory and 120k data memory reasonable? Seems a little high to me. Without too much eCos experience, I might have expected about half the program memory and 1/4 the data memory. -- Alf Katz alfkatz@remove.the.obvious.ieee.org

I have a serial device that is using MCU's UART (rs232) for data transfer, every time my device is suppose to deliver 20 bytes making it a single transaction. We have a VB and C# app using MSCOMM and it works perfectly. Now I have added an Ethernet converter to convert serial data to TCP/ IP packets. It works atleast for half of the time. For the rest of the problematic half the behavior i...

I'm still using slip to connect it to my PC, but recently I'v come to realize how much simpler life would be if I used 10baseT Ethernet.

And, reliable delivery (...

Hi all. I am looking for a add on card/circuit to be able to add tcp/ip to my micro. I can only see myself using a few and not a huge production run.

However I also found PRONIC15 and wondered if anyone has used one? It has a serial port to connect...
