how to control serial port and parallel port and which software?
hello guys
i wont to make a software to control serial port and parallel port
which software i make this software
i learn only c language.
YOU make the software using the C language.
Geez -- you sound like my LAN "engineer" -- "hi dere, i lan engineer, i need know how design lan, you tell me." No, I'm the Tech -- you design the LAN and I put it in accodring to your design. I do not design the LAN, that is what you are paid to do.
Port Splitter: How to share dataflow of one COM port among several applications
As soon as the necessity to work from several applications with a device connected to COM port arises, a person faces problems. The point is that the operating system allows to access COM port to only one application simultaneously. Many issues were encountered concerning the way of accessing the same COM port from several applications simultaneously.
The tickling point was that there was no standard way of doing this due to the limitation of the operating system. This article will consider the only solution to share one serial port among several applications with the help of a com splitting software: Serial Port Splitter.
This program allows to get access to a device connected to a COM port from several applications simultaneously. It creates virtual COM ports that are the exact copies of the specified physical COM port. Now, any program can work with its own virtual COM port not hindering other programs. Data written to physical COM port get to all the virtual COM ports. And vice versa, the data written to virtual COM ports gets to the physical one.
Serial Port Splitter is meant to do the three things: splitting, sharing, joining.
- Splitting. This function allows to create virtual COM ports that are the exact copies of specified physical COM ports. All the data written to physical COM port get to all virtual COM ports. Data written to a virtual COM port get to physical COM port. In such a way, by means of virtual COM ports, several applications can exchange data simultaneously with the same device connected to a physical COM port. At the same time, there is a possibility to configure ports access permissions, COM ports settings and so on.
- Sharing. It is possible to work with the same COM port without splitting it to several different virtual COM ports.
- Joining. If it is necessary to write the same data to several physical COM port from one application, this task can be accomplished using this feature. The program creates virtual COM port and forwards serial data from it to several physical COM ports.
It is also possible to access permissions. Sometimes it is necessary to limit access to a COM port for several applications (e.g. some programs are to only read data from the COM port and some programs need full access to the COM port). Port Splitter supports such function.
Target groups of this program are various. Mostly it is used by GPS devices users, allowing to get data from one GPS-receiver by several applications simultaneously. Serial software developers use Serial Port Splitter as well. It allows to speed up the development process during debugging and data-logging period. Serial Port Splitter allows IT integrators to create solutions that seemed impossible earlier.
