Device manager list only physical PORTS, such as #9-pin/25-pin serial ports and parallel (LPT1/2) ports that you would #physically connect devices such as external modems and printers to the #back of your computer. a COM port is acually an address occupied by the #device, such as your USR mode. COM3 means that your USR modem uses the #next available memory address 03E8h known as COM3 in more simpler terms. # #So YOU SHOULD NOT have a COM3 under ports in device manager, since your #USR Modem is using it and NOT a physical port as describe above. # #Psykosonik # Not so, MSD shows my modem (a GVC 14.4 on com1) as a 16550 uart ,and my com2 as what it is (an 8250),and doesn't recognize com3 (although my software that uses it, recognizes it.) MSD will recognize com3 if I run a program like ADDPORT. Your internal modem ,although it most likely doesn't have a physical UART on it, the BIOS, and software see it as a serial port.(You don't set up your comms software up any differently for an internal than an external, do you? ) I have actually seen an internal modem that had an actual 8250 UART on it (it was a 1200 Baud). Gary Tait , VE3VBF - Please quote prices in $CDN, as $US prices are no good to me ,here in - - Canada. If you must quote prices, please quote prices from dealers in - - the Toronto, Ontario area,and westward.(my location is near Kincardine)
