Hell sluggers...
Heres another problem I might not be able to work out...
I have a GPS and want to log its output onto a computer in simple NMEA format.
The GPS outputs a comma delimited data stream which contains text and numbers, usually in the format of a code for the data type and then the data itself, this is usually five alphas followed by the pertinant data with commas.
I pulled out my trusty old toshiba t1100 + (15 years and it still goes!) and logged the data successfully via the onboard coms port - you know - a DB9 connector, this was using MS-DOS 3.2, which is grand but I want to do it with my newer laptop running mandrake 9.2 - it has more disc capacity and processing power.
To do this I need to convert the DB 9 pin to a USB input, I need to read the USB port at 4800 Baud for it to be readable, and to top it all off, I need to be able to write this data to a file - say every 10 minutes, simple text would do.
So, How can I do it??
I think you will need a USB -> Serial adaptor, USB is a lot more complicated than just a very fast serial port.
After that, it sounds like a job for Python!
