One item I found in searching the nets is a usb to DUAL Rs-232 adapter.. Outragous price IIRC but nice to know it's out there.
I see a lot of computer to rig interfaces but to do it right I need audio and at least TWO, count 'em TWO RS-232... and on the TS-2000 the RS-232 port is dual function as well so it can get real confusing.. If I use the built in mini-TNC that uses the RS-232 port.. And if I use the computer to either control, or to simply read out, the frequency and mode.. That too uses the same port on the computer... Alas only one task can occupy the port at a time.... Thankfully the computer has a full TNC package on board (Which is better than the mini-TNC anyway)
