Delphi Xe Serial Port Component To Hdmi
The Windows Standard Serial Communications Library for Delphi (WSC4D) is an serial communication library based on the Windows API. Includes 46 functions plus modem control, serial comm API. WSC4D uses the core Windows API to communicate with any device connected to a serial port from within a Delphi application. Serial Port component for communication with external devices. Serial Port ActiveX Control is a powerful component that lets developers quickly and effectively work with serial port. Use Serial Port component to easily communicate with external devices on RS232 connection, such as modems, bar code readers, PBX and so on.
Monitor Serial Port To Hdmi
I'm creating a simple program in Delphi, to send character through COM port using 2 parameters, the first parameter is the port number and the second parameter is the character to be sent. So if i save it as p.exe, 'p.exe 20 A' will send 'A' through COM20.

And I also using hyperterminal with the same COM number baudrate=9600, flow_control=none and it gives the same result. The character sent well.The problem is, I cant run my program (p.exe) before I do the following steps each time i logged on to my Windows XP: Connect through hyperterminal to the designated COM, disconnect it.then my executable can be run. Otherwise, just like you run two session of hyperterminal in the same COM, it wouldn't work. Anybody got a hint bout this? Did I miss anything in my code?

I don't see any setup stuff in your code. So maybe you're relying on a side-effect of running HyperTerminal that 'primes' the port for you. Have a look at this article where they go through that stuff: baud, parity, etc.
It seems to be a full working example. See if you can get that working, and use as a base to build from.
Chris ThorntonChris ThorntonYou need to use setcommstate for setup baud rate and flow control.

Erik Salaj from Winsoft has a com port component for Delphi XE6 Firemonkey on OSX available. This is the latest com port component in a series of com port components that he has available for Windows, Android, and IOS. The implementation is pretty basic with the demo application that comes with the component reading data using a timer. However, if you need to access a device plugged into the com port on your Mac OSX machine this seems like a really good solution. Additionally, because of his other ComPort components available for the other platforms that Delphi XE6 Firemonkey supports it makes this a good cross platform solution for accessing the Com Port from one codebase. The component has a free trial and it is a commercial component but is reasonably priced. Additionally, all of the components from Winsoft can be had combined into a giant component suite for a really good price.
