- Just thought I'd give a quick review of the USENET Serial Board II.
-
- I bought the kit, built it myself, the directions were good, all
- parts are socketed, the board is a 2 layer 1/2 slot 16 bit card.
-
- Took me about 2 hours to put it together, set it up as a standard
- dos card (2 ports on 2 irq's) and booted linux. It recognized all 4 16550's,
- and immediately made use of them. I tested all 4 and have no problems 8-).
-
- The board seems very configuable allowing all ports on a single irq
- (each status is or'd together), and any other number of configuations
- involving irq's 2,3,4,5,10,11,12,15, and the standard I/O addresses, or a
- configurable block of 24 addresses just about anywhere.
-
- There is also a status byte for the status of all 4 16550's to make it easier
- to figure out which buffer is full when they are all hooked up the same IRQ.
-
- Manual is fairly complete, including NASA's soldering guide, 16550 complete
- data specs, PAL equations, circuit schematic, cabling diagrams etc.
-
- So basically it looks well designed, includes source code, works well,
- and most importantly compatible with linux.
-
- Now if only I could find a graphics card as well designed/documented.
-
- Anybody out there written a driver to handle all 4 ports on a single IRQ?
-
- Email with any additional questions.
