I need TTL.
I have RS232
I have USB
I do not have a RS232 port. Rules out the standard USB to RS232 dongle.
I think that I want to take an old cell phone to computer interface that has
a USB to RS232 level converter. It is a common chip, and I have the drivers.
I want to take the RS232 from the cell phone cable and feed it to a MAX233
to get TTL in/out.
Then use the TTL to talk to the IC706m2g to control the radio.
Without reinventing the wheel, is there a "better way"?
