[chirp_users] FTDI good - not FTDI bad

[David Buss]

I use my usb to serial adapter to connect to and program Fire alarm panels. I picked up a fantastic adapter recently, works with everything. It's from usconverters.com

I used Keyspan - Tripplite converters, with Coastal Explorer under Win7, 
for a while. At some point, however, they just didn't get the job done. 
It's a pity, as they were good when they were Keyspan products. Gotta 
wonder if Tripplite "improved" things.
