Transform "blk/" folders into "blk.fs" text files Working in "blk/" folder from a modern system is harder than it should be. Moving blocks around is a bit awkward, grepping is a bit less convenient than it could be, git blame has troubles following, etc. In this commit, we modify blkpack and blkunpack to work with single text files with blocks being separated by a special markup. I think this will make the code significantly more convenient to work into.

rc2014: de-buffer MC6850 and SIO drivers The buffer's implementation wasn't buying us much in exchange for its complexity. A modern machine was still too fast for it (copy/pasting text from a modern machine would send bytes too fast for the RC2014) and in the (theoretical so far) case of COS-to-COS communication, the buffer didn't help in cases where the baud rate was faster than the processing of each byte received (for example, if the byte was written directly to EEPROM). I'm scrapping it and, instead, use the RTS flag to signal the other side when we're ready to receive a new byte. Also, implement driver for channel B in SIO. I will need it to talk to my TRS-80 4P.

Make KEY non-blocking ... and rename it to KEY?. Then, add KEY from KEY? for its blocking version. I need this for an upcoming Remote Shell feature. If a Collapse OS system remotely controls another shell, it needs to be able to poll both the remote system and the local keyboard at the same time. A blocking KEY is incompatible with this. In some places, the polling mechanism doesn't make sense, so this new KEY? always returns a character. In some places, I just haven't implemented the mechanism yet, so I kept the old blocking code and added a "always 1" flag as a temporary shim. I have probably broken something, but in emulators, Collapse OS runs fine. It's an important reminder of what will be lost with the new "dogfooding" approach (see recent mailing list message): without emulators, it's much harder to to sweeping changes like this without breaking stuff. It's fine, I don't expect many more of these core changes to the system. It's nearly feature-complete.

A modern machine was still too fast for it (copy/pasting text from a modern machine would send bytes too fast for the RC2014) and in the (theoretical so far) case of COS-to-COS communication, the buffer didn't help in cases where the baud rate was faster than the processing of each byte received (for example, if the byte was written directly to EEPROM). I'm scrapping it and, instead, use the RTS flag to signal the other side when we're ready to receive a new byte. Also, implement driver for channel B in SIO. I will need it to talk to my TRS-80 4P.

Make KEY non-blocking ... and rename it to KEY?. Then, add KEY from KEY? for its blocking version. I need this for an upcoming Remote Shell feature. If a Collapse OS system remotely controls another shell, it needs to be able to poll both the remote system and the local keyboard at the same time. A blocking KEY is incompatible with this. In some places, the polling mechanism doesn't make sense, so this new KEY? always returns a character. In some places, I just haven't implemented the mechanism yet, so I kept the old blocking code and added a "always 1" flag as a temporary shim. I have probably broken something, but in emulators, Collapse OS runs fine. It's an important reminder of what will be lost with the new "dogfooding" approach (see recent mailing list message): without emulators, it's much harder to to sweeping changes like this without breaking stuff. It's fine, I don't expect many more of these core changes to the system. It's nearly feature-complete.
