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

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

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
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
