WebRS-232 Connections. A straight-through cable is used to connect a DTE (e.g. computer) to a DCE (e.g. modem), all signals in one side connected to the corresponding signals in the other side in a one-to-one basis. A crossover (null-modem) cable is used to connect two DTE directly, without a modem in between. WebRS-232 is a simple serial communication standard in which one bit of data is transmitted at a time over a serial cable at the relatively slow rate of up to 20K bits/second and distances up to 50-ft. By specifying the voltage, signaling, pin wiring and control data between a host device and a peripheral, the RS-232 standard ensured that devices ...
