Good morning all,
I have multiple amateur-radio transceivers which may be programmed
with computer software through a USB cable connection. There already
exists various software applications to perform those tasks, however,
most, if not all, are either inaccessable or very difficult to use by
blind amateur-radio operators.
My goal is to develop software that is as easily used by blind
amateur-radio operators as it is by sighted users.
I am a retired software developer so I believe I can develop a
suitable user interface, however, I need to overcome two major
challenges which I never encountered in my professional career. I am
hoping that someone out there can provide some direction as to where I
can start mastering the two following challenges.
1. I have never written code to access external devices via USB
connections.
2. I have no clue as to how to read/write to external devices for
which no technical details are available.
I need at least a starting point which I have been unable to discover
through several searches on the internet.
Any and all suggestions/assistance will be appreciated! Thanks for
your consideration!

Hi Bob,
There is no need to deal with low-level USB or the various CAT
interfaces - the incredible hamlib C library already does this for you
and supports 140+ radios:
https://hamlib.github.io/
The open source cqrlog program is written in Free Pascal and uses
hamlib, so that may give you an example of how to wrap the hamlib
library with a pascal interface:

Hope this helps,
