If the network implementation supports packet reassembly (packets larger than MTU), there may not be a need for a stream (...) (26 years ago, 14-Apr-99, to lugnet.robotics.rcx.legos)

The main advantage I see in it is the ability to change the degree of checking it does on your behalf to ensure packets (...) (26 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

From what little I remember about the Lego protocol, here are some thoughts. *) On reception, some Lego packets may contain data which look like the beginning of a legOS native protocol frame. Most likely, the checksum would fail (once enough (...) (26 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)
