Ethernet can receive at up to 70MB/sec, serial might be able to transfer that data at 10KB/sec but MMBasic might be only able to process the data at a fraction of that rate (depending on what is required). The result could be a lot of lost data unless the Ethernet module can do most of the work.Geoff The Ethernet module (or at least my one) is specifically designed as a serial to Ethernet adaptor, and handles the throttling of data it's self. The serial port that connects to the Maximite is set to a baud rate that matches the Maximite and limits communication to that speed. It has some internal buffering, but ultimately the sending device will be limited to the same speed through the implementation of the virtual com port at the other end. I also support hardware flow control, so it would be possible (from my perspective) for the Maximite to use another I/O pin to throttle the data. Personally I will be happy with serial comms at almost any speed, even if it is capped at 1200bps (approx 0.12kb/s) or even lower. To me it's about remotely communicating small bursts of data over a convienient infrastructure, not pumping high speed data at it.
