I have Duemilanove and Uno boards to work with. The Duemilanove boards give me no trouble, but with one piece of data acquisition software ("ModCom" from http://www.weedtech.com/software.html
Weeder Technologies) refuses to talk to the Uno.
I got the following reply from Weeder Tech (who've never heard of Arduino):Maybe it doesn't support the options that ModCom uses such as:
type = RS232
baud rate = 9600
bit length = 8
stop bit = 1
binary = true
flow control = off
DTR = disabled
RTS = disabled
If any of these settings are not supported, ModCom will respond with "The port can not be openned".
So my question is this: How do I check and/or modify these serial port settings of the Uno? I have installed the latest 8U2 code from bithub, but that didn't help.
