I don't believe there's a buffer, and that the characters are printing out as they're read. If I touch the chip, the floating inputs change states, and it's immediate. Those inputs bounce high and low while I'm touching the chip, then drop have to low when I let go. but, even if I hold the contact closed for even a minute, there's no change. I've tried the M119, with the button push and button not pushed, Results always the same..... So I'm thinking I've programmed something wrong on the chip. (I'm using an ATMEGA2560 board to program the Sanguinololu.) I installed the bootloader, I've installed marlin, then I see all this talk about 'setting the fuses' but none of the programs I've used seem to be able to find my Sanguinololu (whether it's hooked directly to the usb, or hooked through the ATMEGA2560.) (I just bought an USBTiny programmer, which I hope will give me more control over programming the Sanguinololu, but it won't be here till Monday....)
