I assume the calculation of silent interval in 9600 bps is as below.
1 / 9600(bps) * 11(bits) * 3.5(ct) = 4.01 [ms]
A certain manufacturer's slave device calculates as below because Modbus-RTU is binary.
1 / 9600(bps) * 4(bits) * 3.5(ct) = 1.46 [ms]
The both seem to be reasonable, but I would like to know which is correct calculation.
