Title Are reads from serial port limited to 1500 bytes?

Issue Are reads from serial port limited to 1500 bytes?


Solution There is a buffer setting for Dev.ser that defaults to 2048 bytes, and if the timeout is at a shorter time it won't fill that much before it times out, thus generating something like 1500 bytes.

Please try changing the values in Dev.ser.
