Asus WL-500W serial to USB cable

Following an upgrade of Debian on my Asus WL-500W I had an unbootable system. Restoring from backups gave me some breathing space but I really needed to move forward with the Debian upgrade and find out why the system was not booting. Some instructions and some online and in-store purchases had me up and running just two days later.

• Wires, 200mm terminated with pins (FS70M)
• Heat shrinkable tubing, 1.5mm (BF86T)
• Connection pins, 4-way (YW11M)
• Soldering iron and heat blower (N13AR) with some butane (N59AN)
• TTL to RS232 serial signal converter (MAX3232 chip)
• RS232 to USB serial signal converter (FTDI chip set)
