- Greenleaf Comm++ paves the way to robust
object oriented programming of serial communications in applications for a wide range of
platforms - you get platform independence. Comm++ includes abstract base and derived
classes which perform all of the functions needed for your communications jobs. Comm++
removes the grunt work - so you can do your job easier, faster, even better
Platforms,
APIs
- Supports Windows 3.1x, NT 3.5x, Win32s, MS-DOS,
NASI for Novell NACS Server, DESQview, Borland PowerPack™, Tenberry DOS/4G™, and
Phar Lap TNT DOS extenders
- Pure C++ class library with an arsenal of over 460
public calls in the API gives you the industry’s most extensive shot at both rapid
application development and extending or customizing the library for your needs
Power and versatility
This class library
provides powerful tools for all aspects of asynchronous comm programming for all major
PC-based platforms. Combine file transfers with Hayes modem controls, add ANSI, VT100,
VT52, or "glass teletype" terminal emulation, select an appropriate screen
driver and a platform driver
You can drive any number of simultaneous ports on
standard or intelligent multiport boards!
Select XON/XOFF, RTS/CTS, or DSR/DTR handshaking,
along with powerful file transfer protocols!
You can select screen drivers and add onto the
base classes yourself to create entirely new communications functionality for your
applications! Start with Comm++, end on time, within budget!
Sophisticated building blocks
Comm++ begins with
abstract base classes which could be any kind of serial communications - not necessarily
hardware - and builds onto this support for the INS8250 series UART, DigiBoard standard
and intelligent boards, Arnet and Star Gate intelligent multiport hardware, and interfaces
with Microsoft Windows
Your application will first create an instance of
one of the platform / hardware classes, GFI8250, GFDigiPC, GFComOS2, GFComWin3,
GFComWin32, GFSmartDigiBoard, GFSmartArnet, GFSmartStarGate - or the Novell NASI driver,
GFNasi
Then you need to create a generic serial port
control object of class GFSerial. This combination forms the basis for any kind of program
using asynchronous communications
Classes like GFVt100, GFAnsiTerminal, GFTeletype,
and GFVt52 are derived from GFSerial, so all you need do to implement an ANSI terminal in
the above program is substitute one line of code and add one to define the type of display
driver you want to use, as illustrated below:
Easy to use
Below is a short program that runs under MS-DOS
that provides full-duplex 9600 baud communications on COM1.
#include
#include "compplib.hpp"
main( void )
{
int c;
GFI8250 sio( COM1 ); // serial port on COM1
GFSerial cp( &sio );
// open the port
for ( ; ; ) {
if (gfkbhit() {
c =
getkey();
if (
c == ESC )
return;
else
cp << c; // output to port } cp> > c; // get char from port
if ( c != GF_TIMEOUT ) // display
input
putc(
c, stdout );
}
}
To switch to an ANSI terminal emulation, do this:
Add:..............GFScreenVid vid;
Change:.........GFSerial cp( &sio)
To:................GFAnsiTerminal cp( &vid, &sio )
