The only time I used telnet was in order to set a value in the simulator. You can control the data rate of the data pump via command line switch. Check out the README.IO file for information on how you can use it. Another thing to consider is setting the the baud rate on the Arduino to 250000. I'm not sure on the Mega, but the ATMega328 chip has a 0% error rate at that baud rate setting g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind. http://www.simpits.org/geneb - The Me-109F/X Project ScarletDME - The red hot Data Management Environment A Multi-Value database for the masses, not the classes. http://www.scarletdme.org - Get it _today_!
