Serial to USB on Lion with Minicom and PL2303

I’m using a Trendnet TU-S9 which I bought on amazon for $18. It uses the Prolific Driver (PL2303). I chose this one because it works natively on current linux kernels (2.6).

TU_S9Now I’d like to use it on my 13″ Macbook Pro running Lion.

I installed the driver from here (snow leopard only)
Then I installed the minicom package found here. (or use macports)

Now we need to configure minicom.
Run /opt/minicom/current/bin/minicom -s
Serial Port Setup -> A Serial Device
/dev/tty.PL2303-000013FA  (hit return afterwards, not escape!)
Serial Port Setup ->  E Bps/Par/Bits
E:9600 & Q: 8-N-1
Save setup as dfl

Run /opt/minicom/current/bin/minicom to use it, or link it so it’s part of your path:
sudo ln -s /opt/minicom/current/bin/minicom /usr/bin/minicom

If there are no good devices in /dev/tty.* then you may need to add the kernel extentions from

ln -s /opt/minicom/current/bin/minicom /usr/local/bin/minicom
