Emulate a COM port from USB connection?
Hope I'm asking the right question ...
I have an older application (circa 2002) that connects to a VHF radio thru a serial or USB cable. The software only has provisions for communicating with the radio thru COM's 1 thru 4. Is there some way to emulate or dedicate a COM port thru a USB connection? |

This is one of many devices that provide a serial port from a USB connection. -- Richard G. Harper [MVP Shell/User] * NEW!

Emulate a COM port from USB connection?
Thanks for the prompt reply Richard.
The problem is not that i need a serial adpator, as I guess a virtual COM port. The cable I have has a USB connector on one end, with the other plugging into the radio. Is there any way to tell Vista that a certain USB plug is really a COM port? |

The USB to COM port interface needs a Vista-compatible device driver. |

The original author of the software is no longer in business, so I can't ask them. Is there such a thing as a generic driver for this sort of thing? |

There's no way I know of to turn a USB port into a serial port. They use
two entirely different communications protocols. -- Richard G. Harper [MVP Shell/User] * NEW!

Looks like I'll have to find out what the trick is then. The new cable they sent me has a USB plug on one end, so there must be some way to get this to work. I'm just not griting my teeth right! |
