Los puertos serie modernos se utilizan en instrumentos cient\u00edficos, sistemas de caja registradora y aplicaciones como sistemas de maquinaria industrial.<\/p>\n<p>En comparaci\u00f3n con un puerto paralelo, la velocidad de transferencia de datos de un puerto serie es m\u00e1s lenta.<\/p>\n<h2><span id=\"definicion_de_puerto_serie\">Definici\u00f3n de puerto serie<\/span><\/h2>\n<p>Normalmente, un puerto serie es un puerto macho, mientras que un puerto paralelo es un puerto hembra. L<strong>as configuraciones de recursos del sistema se eligen para cada puerto y se identifican por COM1, COM2, COM3, COM4,<\/strong> etc. Cada posici\u00f3n COM representa una direcci\u00f3n de entrada\/salida (E\/S) y una direcci\u00f3n de solicitud de interrupci\u00f3n (IRQ). La direcci\u00f3n de E\/S transfiere y recibe datos hacia y desde un dispositivo perif\u00e9rico, como un rat\u00f3n o un teclado.<\/p>\n<p>El est\u00e1ndar del puerto serie es RS-232. Esta norma se utiliza para transmitir comunicaci\u00f3n serie entre dispositivos, que s<strong>uelen denominarse equipo de comunicaci\u00f3n de datos<\/strong> (DCE) y equipo terminal de datos (DTE). El puerto serie utiliza un conector de nueve patillas (DE-9) o un conector de 25 patillas (DB-25). Originalmente, el est\u00e1ndar utilizaba 25 patillas. Como muchas de las patillas no se utilizaban y eran bastante voluminosas, se populariz\u00f3 el conector DE-9, m\u00e1s peque\u00f1o.<\/p>\n<p>Para la comunicaci\u00f3n serie se necesitaban comunicaciones de mayor velocidad, como unidades externas de almacenamiento de datos. En 1998, el Bus Serie Universal (<a href=\"https:\/\/www.techopedia.com\/es\/definicion\/bus-serie-universal-usb\">USB<\/a>) y FireWire introdujeron interfaces m\u00e1s r\u00e1pidas. Esta nueva tecnolog\u00eda pod\u00eda transferir datos a altas velocidades en el mismo bus, llamado conexi\u00f3n en cadena.<\/p>\n<p>Hoy en d\u00eda, el puerto serie se utiliza poco, pero puede encontrarse como dispositivo de comunicaci\u00f3n para receptores GPS, pantallas de texto <a href=\"https:\/\/www.techopedia.com\/es\/definicion\/pantalla-led\">LED<\/a> y LCD, esc\u00e1neres de c\u00f3digos de barras y monitores de pantalla plana.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00bfQu\u00e9 significa puerto serie?
