Hi, I am working on increasing the speed of data transfer between two electronic modules(each running OSE operating system)using PPP(supported by OSE)over RS485. However be the baudrate i configure the maximum speed i get is 8KiloBits per second. Even if the baud rate has been changed to 38400kbps or higher it does increase the transfer rate. Is there some reason why it doesnt?It will be great if someone can help on this.

Are you using the longest packets allowed? I would hook a scope up and see if there are big gaps in the datastream, then look at any timing adjustments you are able to make. -- John Devereux
