I have developed an embedded application which requests status information from a device down a communications channel. My customer requires that these will be sent with a specific time period, so what I am looking for is a PC terminal application which can send a text string command repeatedly at a set interval over a period of time. I currently use a serial device tester which can immediately send back a set string when something is sent to it, but I need to control the time period and number of repititions.
Are there any applications (for Windows) out there which can acheive this?

In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel.
The serial terminal emulation program is used for the serial communication between the host computer and an embedded system (Target). It is mainly used as a user interface for debugging embedded system. It is also used for sending commands, displaying result, loading firmware, logging result, etc.
Docklight / Docklight Scripting For testing applications communication over the serial port it is the best tool for the job. It listens for user defined sequences on serial port and can then trigger a transmission with parameters derived from the input message or function in a script.
I wrote a C++ program to test a embedded serial application and it was +/- 1000 lines of code. I was able to replace this with about 20 lines of vb script in Docklight Scripting.
Docklight is definitely worth the money.
