Free com1 software for windows

Async Toolbox is a freeware interrupt driven communications library for C. Baud to 115200,COM1-COM4, simultaneous 2 port operation. Includes DATAMON.EXE: used to interface 2 serial devices, capture data, shows logic status of lines, and has an autobaud detection mode. Register for full source code, Digiboard (32 ports), 3 other utilities, prototypes, make files, batch files to create all memory models, Borland C & Microsoft C.
This package of asynchronous communications tools for IBM (COM1-COM4) and Digiboard (intelligent communications hardware, up to 32 ports) hardware, consists of library (.LIB) files for each memory model and for both IBM and Digiboard hardware. It also includes all of the source files, header files (with prototypes) and MAKE files needed to generate the various libraries. Batch files are included for calling make with appropriate flags for each supported compiles.
The "shareware" version comes with the small memory model library only (ASYNCS.LIB). Header files with module prototypes for the library routines are included. A test program (TEST.C) is included for testing the library on your system, and demonstrating the ease of use of the tools.
No other source code is provided with the shareware version or support for Digiboard hardware. Shareware versions are available for Borland C (C++) and Microsoft C (C++).

This program is a demo application for BitLevelGPS software library that provides a PC-based user application with access to a NMEA-183 compliant GPS receiver via a serial communications port. It provides navigational data update once per second, decoding NMEA sentences: $GPGGA (Global Positioning System Fix Data), $GPGSA (DOP and Active Satellites), $GPGSV (Satellites in View), $GPGLL (Geographic position), $GPRMC (Recommended Minimum Specific GNSS Data) and $GPVTG (Course over Ground and Ground Speed). Decoded parameters include: UTC time, date, position (lattitude, longitude), altitude, speed, course, heading and information about visible satellites. Applications include Navigation, Security, Telematics, Fleet Tracking and Asset Tracking. The library provides an interface over serial ports COM1 - COM8.

Why FtpLabyMaker is so special ? Oh just because it knows some special tricks to create locked files or directories on IIS servers or some Unix servers. A locked file is a file with a non-allowed filename containing, by example, special Windows devices like com1, prn, lpt4 etc. Another trick is to add spaces at the begining or the end of the filename. Classical ftp-clients cant deal with these locked files. But its not finished because FLM is designed to browse labyrinths made of locked-directories and during that browsing it can clean the site (deleting files, directories) or even locking it. Its not finished because FLM can also create large and deep locked and tagged labyrinths to make your friends or worse ennemy crazy !
