Fix incorrect timing between data frames #93

Closed ZaTeeman closed 8 months ago

ZaTeeman commented 8 months ago

Library makes an insufficient period of silence between messages in modbus rtu master mode. This fix calculates the required delay after sending the previous message based on the UART bus baudrate. (only for ENABLE_TCP == 0 ) The delay between messages is selected according to the ModBus standard.
