COMM-DRV/LIB
is simply the best, fastest, and most comprehensive serial communication library and DLLs on the market.
The serial communication libraries support
Windows XP, Windows 2000, Windows
Me, Windows 98, Windows 95, and Windows NT, MS-DOS, Windows 3.x. It was designed by real
engineers & developers for real engineers, developers, and
programmers.
We know your time is valuable and have made every effort
to make the product easy to use. You will be able to get started with your
project immediately upon installation. We include Visual C/C++, Borland
C/C++, Access, and Visual Basic example projects that compile and link by
just clicking on the project. Use these as your starting point and in no
time you can have your app performing RS232, RS422, and/or RS485 serial
communication.
For engineers who must work on embedded systems or other
applications dependent on MSDOS, we have ample examples for using
COMM-DRV/Lib with QuickBasic, Professional Basic (e.g, Microsoft PDS
7.x), VBDOS, and Microsoft & Borland 16 bit C/C++.
If you are not using any of the tools mentioned above, it
is still quite possible that COMM-DRV/Lib is compatible with
your tools, as any tool or application capable of calling the Windows API
can call our DLLs (e.g, Magic, PowerBuilder, Visual FoxPro, etc).
Click below for easy document navigation:
|
 | Support ALL compilers and tools that can call 16 bit or 32 bit DLLs. | | Support for ALL Hayes compatible modems (AT
command set). | | Supports ALL single or multiport cards that
include a Windows driver. | | Any number of ports may be active at the same time. | | Built-in hardware and software handshaking for flow control (DTR/DSR, RTS/CTS,
XON/XOFF). | | One API to learn. Same for Windows XP, Windows 2000,
Windows NT, Windows Me , Windows 9 8 , Windows
3.x, & MS-DOS. | | Adjustable communication buffers of any size. | | Remap baud rates logically. Modify baud rate divisor for non-standard baud rates. | | Only library that really allows you to combine different multiport cards in one PC. | | Supports USB to RS232 converters and USB modems with
their respective COM drivers. | | Extensive statistics on every port(bytes lost, sent, received, errors, etc.). | | Asynchronously call user 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). | | Support for all memory models compatible with Microsoft and Borland C/C++ compilers, and
many other compilers. | | Automatic UART type detection; 16650, 16550 support (including FIFO). | | Nondestructive reading of data (read ahead). | | Support baud rates in excess of 460K baud, with the ability to use today's
high-powered communications devices. | | State-driven file transfer libraries allow Xmodem, Ymodem, and Zmodem file transfers on
multiple ports at the same time. | | Completely port re-entrant, allowing it to be time-sliced. | | 16 bit MSDOS/real mode support for most non-intelligent and several well known intelligent multiport cards(Digiboard, Arnet, Boca Research, GTEK, etc.). | | On line help. |
|
| It is not enough to have a great serial
communication product. Good documentation is very important. COMM-DRV/Lib
includes very easy to navigate electronic documentation. Functions are easy
to find and are hyperlinked to related functions. |
 |
 |
For those who must have a hardcopy, we also
have the manual in printed form. |
| Ample examples that illustrates COMM-DRV/Lib's
ease of use. These include Visual C/C++, Borland C/C++, and Visual Basic
fully functional projects. | | 32 bit DLLs compatible with Windows XP, Windows 2000,
Windows NT, Windows Me, Windows 98, & Windows 95. | | 16 bit DLLs compatible with Windows XP, Windows 2000,
Windows NT, Windows Me, Windows 98, & Windows 95, & Windows 3.x. | | 16 bit static libraries compatible with MS-DOS and
Windows 3.x. | | Complete electronic documentation in hypertext format. | | Complete source code to libraries, DLLs, and
examples. | | Excellent technical support. |

I just want to take a minute
to thank you for the software. I’m the one that wanted it for a senior
design class at Iowa State University. It worked great. We gave our
final presentation last Friday and the professors were impressed with our
project. As a testimonial of how easy and well your software works, I’m
an Electrical Engineering student with very little C/C++ programming
experience. In fact I was in the computer science beginning level class
when I began to use the software. Once I got started I had no real issues
with making things work. Again thanks for the
opportunity. Besides going to school I’m working for an equipment
manufacturer that does control systems. I’ll encourage the use of this
software whenever possible. I hope to find other uses for it in the
future.
Thanks,
Brett Stephenson ''Serial communication is at the core of what we do, and COMM-DRV has helped us rapidly
develop new applications, and easily add multiple-port features. We've been very impressed
with the flexibility of COMM-DRV, and the technical support has been outstanding.''
Lee Perryman,Deputy Director and head of technology development, Associated Press
Broadcast Services, Washington, DC
"COMM-DRV from WCSC is a source/object serial communications library for DOS and
Windows that lives up to its hype... its feature set puts it right at the top... In terms
of sheer versatility, COMM-DRV is nonparalleled."

C/C++ Examples |
| The following example is a complete C/C++
application that opens a port, set baud rates etc, dials a phone number,
uploads a file, hangup the phone/modem, and close the port. We did not
put any error checks in the example in order to focus on the application
itself. |
PortHandle=OpenComPort(1,2048,2048);
SetPortCharacteristics(PortHandle,BAUD9600,PAR_NONE,LENGTH_8,STOPBIT_1,PROT_RTSRTS);
Dial(PortHandle,1,"2913603187");
ModemConnect(PortHandle);
cdrvxfer_files(PortHandle,0,6,"*.*",NULL);
ModemHangup(PortHandle);
CloseComPort(PortHandle); |
| The following example simply outputs a
string. |
PortHandle=OpenComPort(1,2048,2048);
SetPortCharacteristics(PortHandle,BAUD9600,PAR_NONE,LENGTH_8,STOPBIT_1,PROT_RTSRTS);
PutString(PortHandle,"Output String");
CloseComPort(PortHandle); |
