244f0dba32 Cleaned up the run loop, less complicated now, and video updates can drive themselves thanks to the new CPU timer functions 2016-08-23 22:41:45 -07:00
Jeff Parsons
97f8e87ca3 Added some iOS usability improvements (related to soft keys/buttons and annoying focus/zoom changes) 2016-08-23 16:08:48 -07:00
Jeff Parsons
2b24e710d2 Fixed the Computer updateFocus() interface to keep the page stable unless fScroll is explicitly set 2016-08-23 14:59:06 -07:00

Jeff Parsons
bca19fd8ed Added proper clocking of VT100 keyboard UART, allowing us to restore the proper CPU speed (2.7Mhz) and maintain the correct cursor blink rate 2016-08-22 09:14:34 -07:00

Jeff Parsons
6a5e18d493 Working on next release (v1.24.1): first change is enabling smooth scrolling by default 2016-08-19 16:10:48 -07:00
Jeff Parsons
23e78b971c Picked up all the last-minute changes from the gh-pages branch (where I discovered a race condition between machines) 2016-08-19 13:03:30 -07:00
Jeff Parsons
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) 2016-08-18 18:49:01 -07:00
Jeff Parsons
5ed8f13840 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).

0e4ad76b94 Cross-machine serial port connections are only half-working (need to defer initConnection() until all machines on the page have initialized their bus) 2016-08-18 11:30:22 -07:00
Jeff Parsons
f0509bc5d1 Successfully running PCx86 and PC8080 machines on the same page now 2016-08-18 10:29:24 -07:00
Jeff Parsons
145ec9d125 Starting on v1.24.0; first change: support for encoding ESC characters in SerialPort test strings (support which perhaps should eventually be moved into getComponentParms() instead) 2016-08-17 19:09:23 -07:00
Jeff Parsons
9d289b54da Dual (connected) terminal configs should be working better, now that both transmitted and received data is clocked according to their respective baud rates 2016-08-17 15:42:02 -07:00
Jeff Parsons

Jeff Parsons
81239cdbbe Dual VT100 bi-directional communication is now limping along 2016-08-16 11:34:11 -07:00
Jeff Parsons
cf24023d5d 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) 2016-08-16 09:34:41 -07:00
