Updated the build process to formally declare that we're compiling from ES6 to ES5 (although for now, 99.99% of the code is already and will remain ES5.1-compatible)

Updated Closure Compiler to v20160911, so now we have a version that supports ECMAScript 6, but I'm not going to go bonkers on ES6 features just yet; the first feature I'm going to use is support for octal and binary constants (of the form 0onnnn and 0bnnnn)

Bumped version to 1.30 in honor of the PDP11 module that's being integrated, along with my first attempt to use a newer version of the Closure Compiler (ie, the JavaScript version), as well as giving Gulp a try -- although Gulp leaves just as bad a taste in my mouth as Grunt did

ff46c1d240
Updated receiveData() to always return true in both PCx86 and PC8080, since both machines are buffering all the incoming data anyway (since we still don't have any flow-control interfaces yet)
2016-08-19 08:42:33 -07:00
Jeff Parsons
b52e794997
Added a (temporary) auto-XON hack to the VT100's SerialPort component to prevent ugly buffer overflows when a PC is shoveling the data in too fast (to be replaced later with real flow-control interfaces)

A (PC8080) VT100 can now connect to a (PCx86) IBM PC AT; only problem seems to be flow control now.
...
Also, each PCjs debugger can now be independently accessed from an external debugger (eg, "pcx86('ver')" or "pc8080('ver')"); the global '$' symbol is no longer used for debugger access.
TODO: There are still many places where GLOBALVAR should be replaced with PCX86.GLOBALVAR or PC8080.GLOBALVAR as appropriate (which I've finally started doing in each debugger.js file).

Enabled smooth scrolling, connected SerialPort UART transmitter status to the ChipSet FLAGS buffer (matching how the Keyboard UART transmitter status is connected), enabled binding of terminal I/O to the Control Panel output window (if any), and added simulation of received data at the programmed baud rate (but a better solution has been noted and needs to be implemented)
