Hello:
I found some post about serial port problems, but I have a strange case.
I have a new Netduino Plus 2, and a RFID reader that sends data via RS-232 in 9600,n,8,1. This reader only sends data, and no need to receive any information or config.
I connected the RFID TX to D0, and GND to GND (I tried with COM1 and COM2).
I use simple code to read the data, and I tested several methods (read byte to byte, all bytes indicated by BytesToRead property…)
When I approach a card to the reader it sends the serial number of the card, but the data is different to the read with Hyperterminal on the PC.
[font="'courier new', courier, monospace;"]Hyperterminal : 02 30 31 30 36 44 30 45 42 32 36 0D 0A 03[/font]
[font="'courier new', courier, monospace;"]Netduino Plus 2: 3F A6 E6 66 E6 F9 EA F6 36 26 CA D6 F2 00[/font]
The number of bytes is correct but the other data is totally wrong.
Any idea?
Thanks for your time!
