Subject: [chirp_users] Alinco DR-235T - "No response from radio" Error

I found this old bug report from several years ago that I thought might address my issue:

https://chirp.danplanet.com/issues/254

I tried changing the baud rate for the COM port I'm using, but it made no difference.

I get the same error whether I'm in clone mode or not.

Any ideas?
