PC-VT - VT100/VT102/VT52 Terminal Emulator (C) Copyright 1984 Mark C. DiVecchio Version 7.6 PC-VT is a software emulator which makes the IBM-PC function as a DEC VT102 or a VT100 Video Terminal. Version 3.0 includes a Hayes compatible dialer and phone number directory. Version 4.0 includes many user suggested improvements. Version 5.0 added XMODEM (CRC capable) support. Version 6.0 added DOS 2 path name support for file upload and download. Version 7.0 added VT52 emulation as a subset of the VT102 mode of operation. The latest version of PC-VT runs on the PC, PCjr, and the AT. - Here is a brief list of the functions handled by PC-VT. * Communication over an RS232 port configured as either COM1 or COM2. * Communications support for all of the popular baud rate and data bit/parity bit combinations. * Full Duplex with no EIA modem control. Only data leads have to be connected (FDX A mode). Suitable for use with a null modem (direct) connection to the host computer or with a modem which does not require modem control signals. PC-VT does send DSR and RTS. * Support for Hayes dialing commands and includes a Dialing Directory with 10 entries. * Support of ALT-F1 thru ALT-F10 as Macro keys. * Support of environment string 'PC-VT=' for finding the location of the parameter files. * VT52 Compatibility Mode. * Full receive parity checking. * Both Numeric and Application Keypad modes. * Full cursor control. * Full feature Upload and Download file capability. Both ASCII and XMODEM (CRC capable) are supported. Path names are supported if you are using DOS 2. ASCII upload features a handshake capability. * Capability to transmit a sustained Break. * NO SCROLL key XON/XOFF support. * Connection of a printer as either LPT1 or LPT2 including local print screen operations. * Capability to echo all displayed characters to LPT1 or LPT2 as hardcopy record of a terminal session. * Using special ALT key keystrokes, access to several special function procedures. * SETUP A and SETUP B displays. * Full XON/XOFF support for both transmit and receive. * ON LINE, LED "L1" and KBD LOCKED lights are supported via the use of line 25 of the PC display as a status line. Four LED lights are supported for the VT100. * For the more sophisticated user, the majority of the ANSI standard and DEC private Escape sequences are supported. * Run DOS functions without leaving PC-VT or disconnecting from the host. - Here is a brief list of what PC-VT can not handle. * Half duplex modes (HDX A and HDX B) and special full duplex modes (FDX B and FDX C). * Features used only in these non supported communications modes. * Test and Adjustments Escape sequences. * Certain display attribute handling for normal and reverse video. The IBM-PC does not handle reverse video (black on white) the same way as the VT100/102. * Functions with no IBM-PC hardware such as Smooth Scroll mode, 132 column mode, Alternate Character ROM modes, and double height character modes.
