It is compiled and linked with the Borland C++ compiler, and supplied in the form of a set of ready to link object libraries. The routines in Serial++ are as easy to use as file i/o in C, yet give you complete access to the registers of the 8250 UART, should you require it. They allow you to read characters from and write characters to two serial ports simultaneously, in a fashion very similar to stream i/o in C. Support for iostreams as defined in C++ version 2.0 is not available as of this release. Implemented as C++ classes, the Serial++ library handles multiple ports and multiple instantiations with ease. The SerialPort and BreakTrap classes contain all the internal housekeeping necessary to deal with multiple instances of the each class using a single port. It is because of this feature that Serial++ lends itself nicely to event driven applications. Serial++ protects your applications from keyboard breaks, (pressing the Control-Break or Control-C keys), to insure that the necessary interrupt housekeeping is completed before terminating,. This guarantees that premature closing of a Serial++ application will not leave your system with invalid service routine addresses hooked to the serial interrupts.. By default SerialPort will perform an orderly shutdown when a break key is pressed, and exit to DOS. You can, however, specify that keyboard breaks be handled in your own application code, in which case SerialPort will continue to operate and ignore the break. See the section on break trapping for details on how this works. You can also use the keyboard break handling in Serial++ by itself. The BreakTrap class is entirely independent of the SerialPort class. Serial++ is linked into your C++ programs just like any other library. There is absolutely no requirement for external TSR's - - applications using Serial++ are completely self contained. 4 Hardware/Software Requirements Serial++ may be used on any PC or PC-AT compatible computer, running on an Intel(Tm) 8088, 8086, or 80x86 family processor or compatible, that uses standard port addresses for COM1 and COM2. It is worth mentioning that Serial++ assumes that your serial port hardware makes use of the National Semiconductor 8250 UART chip, or a clone of it. It is almost unheard of to find hardware that uses anything else, so if you don't know what your serial board uses, you're alright. Be aware of this issue though, if you use some sort of exotic or proprietary serial boards in your machine. When in doubt, try executing the demo program on your target machine. While Serial++ is unaffected by machine speed, and has been run on machines operating at 4.77 to 33 MHz, it does expect to find the serial ports and interrupt vector addresses at very specific locations: Device Base i/o Address Int. Vector Address COM1: 0x03F8 0x000C COM2 0x02F8 0x000B Keyboard: Ctrl-Brk n/a 0x0023 Ctrl-C n/a 0x001B If you have difficulty getting the demo program to work, you might want to consult the technical documentation that comes with your computer to verify the addresses shown above. Serial++ requires MS-DOS, version 2.11 or higher. [The library has been tested and works with version 5.00]. Serial++ uses DOS functions for saving, setting, and restoring interrupt service routine addresses. While it is running, Serial++ traps the interrupts mentioned in the table above. Although it restores the addresses of the prior service routines upon exit, while it is running Serial++ could interfere with any TSR's that utilizes any of the listed interrupts. Consult the documentation of any TSR's you use that provide serial communications or respond to the Control-Break or Control-C keys. 5 Installing Serial++ Serial++ is distributed as a self-extracting archive file, SPP.EXE. The first step in installation is to copy this file into a work directory and execute it by typing: C:>spp at the DOS command prompt. SPP will announce each file as it is unpacked looking something like this: . . . READ.ME . PACKING.LST . SPPL.LIB . BREAK.H . SERIAL.H SPPS.LIB . . . . After you have expanded SPP.EXE into its component files, you may delete it from your install work directory, to save space. The first file to check is READ.ME, which may contain updated information about Serial++. You may also wish to examine the contents of PACKING.LST, which lists every file in the package, along with a brief description. The files included in the Serial++ package fall into the following groups: > Library files, SPPx.LIB. There is one library file for each memory model supported by Serial++. > Include files, *.H. These are C++ source includes that define the public interface of the classes that make up Serial++. > Demo related files, *.CPP, *.BAT, *.MAK, etc. These files are included to provide you with some examples of how to use Serial++. They include an executable demo program, SPPDEMO.EXE, which is ready to run. > Documentation, READ.ME, PACKING.LST, and the file that contains this document, SPPMAN.TXT. In order to begin using Serial++, you must place the library and include files in a directory where the C++ compiler and linker 6 can ting,. Thisright.
