| | | The retry timing for RCX_Link uses a dynamic backoff, which is a good general purpose solution if you're going to be sending lots of packets (like a typical NQC download) and the latency through the serial driver is unknown and/or unpredictable (...)

| | | | | (...) I looked into this a bit more and the poll bytecode (0x12) didn't have a case in the PredictReplyLength() switch. If you add... case 0x12: // poll return 2; then poll will be a lot faster. If you run into other bytecodes that you use a lot, (...) (24 years ago, 11-May-01, to lugnet.robotics.rcx.nqc)

I've made that configurable and at present I'm running with it set to leave the link open. (...) (24 years ago, 11-May-01, to lugnet.robotics.rcx.nqc)

| | | | (...) Correct - dynamic timing is turned off when predictive is being used (which is the default). Predictive is relatively new, and I wasn't sure which code you started with (or how you ported/used it), so that's why I explained the dynamic timing. (...)

| | | | (...) I made PredictReplyLength a member of the RCXLink class so it can return a different value for case 0x20 (it returns 20 if the Target is Cybermaster and 0 if it is Scout - since the Scout doesn't support that opcode). Of course, in Object (...) (24 years ago, 11-May-01, to lugnet.robotics.rcx.nqc)

The return value for an unsupported opcode doesn't really matter since nothing is going to come back anyway, so predictive will fail no (...) (24 years ago, 12-May-01, to lugnet.robotics.rcx.nqc)
