Hi
I’m trying to interface to a Modbus device and since I didn’t get any useful data back from the device, I connected a scope to the serial TX line (data going from the Fez Domino to the Modbus device). The device expects data in 38400 baud, no parity, 8 bits and 2 stop bits, but according to my scope (PicoScope) the data has frame errors. However if I tell the scope to interpret the data as having only one stop bit, I get the correct interpretation.
TeraTerm however interprets the data correctly regardless of how I specify the number of stopbits (I guess it is intelligent enough to switch to the correct format)
Has anyone seen this problem before, and more importantly, found a solution to it?
