Capabilities & Background:
Let me give you a little background about our PC qualifications. Our experience with the PC hardware platform dates back to 1985 when we started working on an IBM PC-XT. (The one that wheezed along at a rousing 4.77 MHz.) The terminal emulation software that was available at that time was pathetic, so we immediately started developing PC-Passport, a CCUR 6312 terminal emulator. We sold the first copy just two years latter in August of 1987. Since then, PC-Passport has sold thousands of copies and undergone continual development. PC-Passport now consists of over 54,000 lines of 80x86 macro assembly language (TASM).
Our PC experience, and the PCs themselves, has advanced greatly over the years. Our current in-house Ethernet network consists of five PCs; Pentium 200, Pentium 133, 486/66, 386/33 and a 386/25, running Windows 98, Windows 95, Windows 3.11, DOS and Linux. The 386/25, running Windows95, has replaced the XT as our performance testbed. We take pride in the efficiency of our software, so we always do final evaluation on a slow machine where inefficiency will really show up.
PC-Passport supports ALL of the original 6312 terminal escape sequences. It works in block and conversational modes, supporting Reliance, Medit, LEX, MTM etc. It includes mouse support to greatly improve access to Reliance and full screen editors. It communicates over dedicated or dial lines at speeds up to 57,600 bps when using the PC's serial port hardware. It also supports BIOS (INT 14) network redirectors at speeds up to 38,400 bps. PC-Passport supports host initiated Xmodem file transfers and extended packet mode. When used with the R06-01 version of XMODEM32 it can perform group transfers using wildcards or a select file. The international version supports the French, German, Spanish, Swedish and United Kingdom character sets.

Extensive experience in low-level IBM-PC programming, including:
| Interception and servicing of interrupts, including cascaded interrupts (IRQ 8-15) |
| Detecting and programming 16550 buffered UARTs |
| Implementing comprehensive mouse support through INT 33h |
| Designing and downloading of fonts for EGA and VGA display adapters |
| Saving then releasing code and data segment memory to make room to run another program |

Major PC Programming Projects:
| Designed and developed PC-Passport, a 6312 terminal emulator with Xmodem file transfer capabilities and extensive script file support. PC-Passport runs on PCs and compatibles and consists of over 54,000 lines of 80x86 macro assembly language (TASM). | ||||||||||
| As a part of a consulting contract, we added touch screen support to PC-Passport and created a customer specific functional variation. The touch screen support allowed the customer to supply specially equipped PCs to hospitals, allowing non-technical users to access the CCUR Reliance database. | ||||||||||
| As a part of a consulting contract, we
made extensive enhancements to the production release of
PC-Passport. We added a full screen editor that is used
to modify the contents of the internal copy buffer. We
designed a packetized error checking protocol to allow
error free transmission of data to and from the host
computer. We added escape sequences that greatly extended
PC-Passport's capabilities. The new escape sequences
allow the host CCUR system to:

| As a part of a consulting contract, we designed and developed a screen editor and terminal server. The screen editor allows users to build and maintain PC text screen images -- both pop-up and full screen. Screens are designed using the keyboard and the mouse. The terminal server translates the PC screen images into terminal escape sequences using a user definable set of terminal characteristics. The terminal server uses screen buffer differences to perform terminal updates using the minimum number of escape sequences. |
