MODE LPTx=COMx
Unfortunately MODE LPTx:=COMx redirects parallel printer output to a COMport, I've never seen any indication that it will work the other way.
For example, to accommodate a 1200 baud serial printer on COM2 to a program that only has LPT1 output:
MODE COM2:1200,n,8,1,p sets up the comport with continuous retry
MODE LPT1:=COM2 redirects LPT1 output to COM2
yes
This cannot be done. The LPT port is a digital parallel printer port used mostly to interface with printers. The LPT port has a very low data transfer speed and is considered by many to be obsolete. The S-video is an analog port and sends a signal similar to a composite video signal. The two are apples & oranges, and there is no known hardware which can make that conversion. Nor will there likely ever be.
LPT is short for Line Printer. So it is a parallel port. The most common type of socket is a DB-25.
old ones use LPT or Printer Port and new ones use USB
Line Printer Port.
LPT (Line Print Terminal or Local Print Terminal) is the original, and still common, name of the parallel port interface on IBM PC-compatible computers. The LPT is now seen less and less due to the USB.
You can an USB port or LPT port.
A virtual port is a software emulation of a port which normally would be present in hardware. This is most commonly used with modems and printers. Many internal modems emulate a COM port. When modems first became common by far the most common type was an external modem which plugged into a serial port (a COM port) in the back of the machine. Nearly all of the early dial-up networking applications were written with the assumption that the modem could be found on one of these COM ports. While it is no longer necessary for the modem to reside on a COM port, most new modems still emulate one in order to maintain compatibility with these legacy applications. Printers can also reside on a virtual port for much the same reasons. All printers used to plug into a parallel port (an LPT port) on the computer. As a result many legacy programs were written with the assumption that any printers would be located on an LPT port. When USB printers became commonplace it became necessary to allow these USB printers to be assigned a virtual parallel port in order to maintain compatibility with these older programs. This can be configured in the OS in the printers settings and is most often used for DOS-level point-of-sale or data-entry applications.
COM port is used to configure a router but you can also get a COM port to USB port adapter which can configure a router using a USB port.
Rollover cable is used.
COM and LPT PORTS
LPT can mean Local Property Tax. The LPT form is not one that is used in the United States. However, residents of countries such as Ireland, are expected to complete an LPT form annually.
