Radio Control: Wonderful RS-232

• Most radios still use RS-232 for programming and control

• Low data rates – 4800 or 9600 bps

• Two types of USB-serial adaptor:

• FTDI FT232
• Prolific PL2032 – cheaper, more common

• Both well supported under Linux

• I find FTDI more reliable; YMMV.

Notes:

Used for setting radio frequency and also reading back manual settings by software.

If the interface is unlabelled, or doesn't say FTDI, it'll be a Prolific.
