Professional successive communication library - DLL for Windows & MSDOS libraries. Features: * State-driven file transfer libraries allow Xmodem, Ymodem, and Zmodem(w / collapse recovery) file transfers on multiple ports at the same time. * Built-in hardware and software handshaking for flow insure (DTR / DSR, RTS / CTS, XON / XOFF). * Asynchronously call user's C / C++ or assembly functions on any successive communication or timed event (experience, channel, modem, or status change interrupt event, cowcatcher count events, specific character reception, mistake events, and much more). * Automatic UART type detection; 16650, 16550 livelihood (including FIFO). * Support baud rates in superfluous of 115, 200 baud, with the ability to habituate today's high-powered communications devices. * Completely port re-entrant, allowing it to be time-sliced. * Complete manual in Help / Hypertext format. HARDCOPY AVAILABLE. * Extensive statistics on every port(bytes lost, sent, received, errors, etc.). * Only library that really allows you to mix different multiport cards in one PC under MSDOS including Digiboard, Arnet, Boca Research, GTEK, etc. * Very easy to habituate (shortstop learning curvature). * Same API for Windows and MSDOS. * Extensive set of examples. Supports: * Microsoft Visual C / C++, Borland C / C++, Access, Visual Basic, Professional Basic, QuickBasic, & altogether compilers & tools that fundament call DLLs (e.g. LabView, Delphi, etc). * Virtually altogether Hayes compatible modems. * Any number of ports running concurrently * Any device that has a Windows successive communication driver (multiport card, USB - successive hubs & modems, PCMCIA). * Windows XP, Windows 2000, Windows NT, Windows Me, Windows 98, Windows 95, Windows 3.1, MSDOS.
