    Virtul Modem (pstn modem emulator) needed

    I use a virtual serial port like: Eterlogic - VSPE: tool for serial ports emulation Run that, then open up a terminal emulator like: Terminal Software Once the two are connected, I can test the concept. Then write another VB program to talk on the virtual port and act as a simulator. Hope...

    Calculating data rate of uart from baud rate...

    Baud rate and Bits/s are not the same thing. Google Baud rate. Baud Rate Baud rate is characters/second. How do you send a charater? 8N1, 8N2 9E1 7N3? Each one is a different Bit/Sec (BPS) but the same baud. Hope this helps Red

    do i need a stepper motor or a dc motor?

    Lets assume the intent of the project is to learn about electro-mechanical systems. You would normally use a DC motor (or AC) and gear it down. Use sensors to know its position. Then use some type of control system to make it work (uP,PLC,RELAY,Discrete, etc.) To make the design simple, I (not...

    Detecting ice in water pipes....by using a motor?

    Here is how to look at the problem. Pretend the ice blockage is a vale upstream in the system. The task is now to detect the state of that upstream valve. So, here is what you do. 1) Place a pressure sensor up stream of your cold water servo. 2) Now, take a reading on the pressure sensor. If...

    Detecting ice in water pipes....by using a motor?

    Where is the pipe generally freezing? Options outside, on an outside wall, at the mixing valve. This problem can be easily solved, but I need to know what mechanism you are trying to ivercome. Red

    C language to Assembly

    True, but..... they may not produce the intermediate files (.lst, or .asm). They may create them as temp files, then delete them. You have to look at the compiler manual to find out how to produce the intermediate files and how to format them. Red
