A very simple device for shifting serial signals at digital/TTL levels to RS232. Works on 3V to 5V supplies and logic levels. 9 pin DCE and DTE connector. There are Tx and Rx indicator LEDs.
This is one of those devices that everyone needs at some stage during embedded systems development!

Tagger is a USB device that connects a PC to a JTAG interface. Data throughput is a respectable 800KBits/second (many times faster than a parallel port). Works with targets of 3 to 5V.
Software interface is through a low level driver. Sample code exists to demonstrate the in-circuit programming of Flash devices directly connected to an Intel StrongARM and an AMD Alchemy (AU1000, 1100, 1500). Sample code also exists to program a small selection of PLDs.
