Hi!
You just need cheap usb-rs232 dongle (ebay $2-$3), one TTL chip 74LS05,
10k and 4k7 resistors. All together well under $10, should say under $5.
I just blow my Ci-V level converter that was made with MAX232 chip and
made new one with those.
Usb-rs232 dongles do not have rs232 specification defined -15V/+15V
voltage. They work with 0V/5V and have 5V power source available
directly so they are ideal for 74-series TLL chips.
There are plenty of similar at Google image search with words: ci-v rs232
Obviously you are Windows user. With linux you could use command socat
to create virtual serial port over TCP that could be solution.

You would think it’s that simple, but no. Icom’s required CT-17
level-converter, at $139, only works with an RS-232 connection on the
PC. USB-9pin converters are evidently not supported.
Very frustrating. This was a top of the line rig not too long ago.
Built-in Ethernet. Built-in RTTY and PSK.
