Professional serial communication library - DLL for Windows & MSDOS libraries. Features: State-driven file transfer libraries allow Xmodem, Ymodem, and Zmodem(w/ crash recovery) file transfers on multiple ports at the same time. Built-in hardware and software handshaking for flow control (DTR/DSR, RTS/CTS, XON/XOFF). Asynchronously call user's C/C++ or assembly functions on any serial communication or timed event (receive, transmit, modem, or status change interrupt event, buffer count events, specific character reception, error events, and much more). Automatic UART type detection; 16650, 16550 support (including FIFO). Support baud rates in excess of 115,200 baud, with the ability to use 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 combine different multiport cards in one PC under MSDOS including Digiboard, Arnet, Boca Research, GTEK, etc. Very easy to use (short learning curve). Same API for Windows and MSDOS. Extensive set of examples. Supports: Microsoft Visual C/C++, Borland C/C++, Access, Visual Basic, Professional Basic, QuickBasic, & all compilers & tools that can call DLLs (e.g. LabView, Delphi, etc). Virtually all Hayes compatible modems. Any number of ports running concurrently Any device that has a Windows serial communication driver (multiport card, USB - serial hubs & modems, PCMCIA).
