Hi Amanda
The defaults should be fine i think. The EB40A uses the at91 serial
driver. This keeps a 128 byte buffer in the driver. Are you running
the serial port at very high speeds? Do you have any sort of flow
control? Are you using anoncvs or eCos 2.0. There was a major rewrite
of the at91 serial driver after eCos 2.0 was released.
