You can get a USB to RS-232 serial adaptor that will allow you (if you get two of them) to have up to 3 Rs-232 serial ports

The computer has two usb ports and one DB9 serial port. This is what I want to hook up. An MFJ-1275 sound card adapter. I also want to run HAM Radio Deluxe and control to radios with the CAT interface. A Yaesu FT- 920 HF and a FT-847 both is CAT capable. I would like to study CAT on the 920 & 847 two serial reports required I have one on the computer? MFJ-1275 to be used on both radios I am thinking a Patch Bay. I will move the cables if needed. I have allot of items that require a serial port and only one, a switch to switch the Items to the one port. Or is there a better way. Can someone help the old "Gunny" KC8SXG Barry ------------------------------------------------------------------------------ No virus found in this incoming message. Checked by AVG Free Edition.
