Hello!
I use 3 UART’s.
I have connect a RS485 Converter to UART 4.
On the RS485 is a SmartMeter with ModBus Communication.
I send a request to this Smartmeter and he answer with the data.
On my PC I tested and all is fine (157 Bytes each answer)
But when I try this on the BeagleBone Black, I just receive 125 - 127 Bytes.
How can i check if my serial Port on the BBB is 9600 8N1?
stty -F /dev/ttyO4:
speed 9600 baud; line = 0;
min = 0; time = 5;
-brkint -icrnl -imaxbel
-opost -onlcr
-isig -icanon -iexten -echo -echoe -echok -echoctl -echoke
Are this settings correct?
Or has someone an idea for this problem?
Thank you!
(btw: I check and send from the PC over RS232 some ASCII to the BBB. All are fine)
