Virgil Dupras 3581beace0 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.		2020-12-29 21:36:19 -05:00
