I had heard that the Key's clock was a little flakey, but I thought it would be enough for Serin cause its supposed to be async. I'll toy with the two resonators that came with my SX tech tool kit. Besides unplugging them before hooking the key up, is there anything I should be aware of when using them? If I can even see them... the numbers on these things are so small its almost impossible to read them. Which would be better for serial communication at 2400... the 4Mhz or the 50Mhz? Is there any harm in having the clock too fast? And my question about True on serial communication is because I've never heard of the terms True and Open... Inverted and non-inverted I get but not True and Open. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=264135#m264230 Need assistance?
