The standard basic board has a transfer rate of 112 kBd. If you wish to
transmit at 1MBaud, then the basic board has to be configured again by our
services.
1MBd configuration: Please consider that the divider factors for programming
the transfer rate do not comply with the PC standard anymore.
The 1M Bd transfer rate can only be programmed with the device drivers
delivered with the board.
RS 485 : transfer at 1 MBaud only works when the transmitter is controlled
through DTR, RTS or data bit.
