I have a new ROM3 IIc (new to me). I soldered the proper connections coming from the DIN5 connector according to the ADTPro documentation.
On the host side, I ran the three wires (Rx/Tx/GND) to a USB to RS232 converter.
A long time ago, I got this to work on my Apple IIe using a variety of adapters to go from DB25 to DB9, etc.
But for some reason, I'm not having any luck with the IIc.
I believe I have everything configured correctly. ADTPro sees the USB/serial port just fine (COM3). I've tried 19,200 and 115k.
The ONLY thing I can sorta make work is when I check the Apple IIc Imagewriter Cable. I know that isn't the right thing to do. BUT, when that is checked, I get a bunch of garbage come across on the IIc side.
When that isn't checked, I get nothing at all.
I've done the IN#2 and <CTRL-A>14B. I've tried 10B, 12B, etc. Nothing seems to work and I cannot remember what all I did when I did this on the IIe.
Any suggestions?
Thanks.

Check that RX and TX are correct--that and ground should get data flowing.

Also check that you have no unintentional bridges in your soldering between DIN pins.
I recently had the same problem when hand soldering a //c DIN 5 plug. You can check continuity from the DIN to the DB9 and everything passes giving you the false belief that your wiring is OK. But check continuity between pins in the DIN and make sure you've got no unexpected surprises (like I did!).. It turns out some of my pin insulation was less than perfect (poor heat shrink application) and when putting the DIN 5 hood on it was causing a bridge between pins. :-(
I just thought I'd mention it, because your symptoms sound very similar to what I was experiencing.

Hi there,
Like suggested you can check continuity across the cable AND between pins on both ends, you could make a loopback to check the serial port on the IIc with a jumper between RX and TX on the cable you made and a terminal program, It have to display any keystrokes you try.

Nothing seems to work.
I've checked all solder points multiple times. Everything looks good. I've tested each pin with a multi-meter on both sides and everything checks out.
I've checked the internal pins of the IIc near the modem port and they look good too.
I've tried the loop-back on the IIc but nothing seems to happen. I type "IN#2" and do the CTRL-A (14B) thing but nothing. I was expecting maybe double characters as I type.
Anyway, the ONLY way I can get characters to come through is if I select the Apple Imagewriter cable and when I do, I get nothing but garbage on the screen.
I'm really at a loss here.
I'm thinking of connecting my IIe up to my SSC and test out ADTPro on that again.
Oh, I've even run ADTPro as administrator (Windows 10) to no avail.
Looks like I may have to make my disks on the IIe for my IIc. :-/

Most of the cheap, no-name USB/RS232 converters are utter crap. Sorry you had
to find out the hard way!

I found this out the hard way, too. I bought three from Monoprice or
some other site. One worked, the other didn't work at all, and the
third had a blob of plastic shoved in amongst the pins. Sheesh. After
applying my Monster Official Plastic Blob Removal Apparatus Tool
Utility ($700 MSRP), that one worked fine.
