directly transmitted by a serial interface or terminal is related to the transmission rate and the electrical characteristics of the transmission line. When the transmission line uses a non-balanced shielded twisted pair with a 50pf capacitor every 0.3 m (about 1 feet), the transmission distance decreases as the transmission rate increases. When the bit rate exceeds 1000 BPS, the maximum transmission distance decreases rapidly. For example, when the

C # serial port control, c # Serial Port The serial port is the standard interface of a computer. Currently, a PC (Personal Computer) usually has at least two serial port COM1 and COM2. Serial interfaces are widely used in data communication, computer networks, and distribut

I read a lotArticleAnd writes are very simple (actually very simple :)). A detailed tutorial is provided. 1. Use vspd to connect two virtual serial ports on the PC. I connect com2 and com3. Click ADDR pair. 2. We can see that two virtual serial ports are connected together on virtual ports. 3. The virtual serial port is ready. First, you can dir

second. A long time ago, 300bps was fast, and now the computer can handle up to 430,800 of the RS-232 rate. The units that represent the baud rate are also KPBS and mbps,1kps=1000bps and 1mbps=1000kbps. In general, when a serial device is mentioned, it is often said that it may be a data communication device-DCE (Communications equipment) or a data terminal device-dte (the information Terminal equipment).

Windows is the host machine, and Linux is installed in the vmwarevm. You can also write a program in Linux to send messages to the serial port. The same principle is to use the virtual serial port software vspm to connect com3 to com4 and then capture it through the serial port debugger. The following is a C sample code for the
