- Sorry about the malignment of the DOS-based UUCP program. I admit: I've never
- actually used one. I do know that I can't call DOS sites for news, though
- (they need to call me) due to UUCP limitations ... but I'm not even sure what
- they're using for UUCP, so ... ! :-)

- Some (most) of this is due to hardware. Standard UARTS will interrupt for each
- character received on a PC. If you use a fast modem (say Telebit Worldblazer,
- which regularly transmits/receives 2000cps), that's 2000+ interrupts per second
- (quite a bit for ANY O/S to handle).
-
- UNIX will have some trouble in this area as well. There are some "patches" to
- this (like 16550AFN UARTS, with a 16 byte buffer), but in the end, you're
- always limited both in throughput and ports.
-
- The solution to this is a "smart" serial card. There are plenty on the market,
- with a variety of expandability and costs. I already have several solutions by
- Digiboard (they're pretty much the industry leader in this area). What they do
- is provide some number of ports (generally 8 or 16 to start with), with the
- ability to expand based on product (one board that I have is expandable to 32
- ports, the other is expandable to 224 ports). Generally, each port can be run
- at very fast speeds (115K bps), and the board guarentees that no data will be
- lost.
-
- I know that Digiboard drivers will be available with the next field test of
- Windows NT, so this will clearly work ...
-
- In UNIX, the Digiboard ports act exactly like a standard serial port, but has
- a different name (like /dev/term/a01 rather than, say, /dev/tty01).
-
- Will UUPC/extended handle "special" hardware like the Digiboard stuff? If you
- try to talk to the serial port via IRQs and stuff, then there will most
- definitely be a problem. If you use standard operating services, then all
- should be well. Except: I don't know much about NT. Are there standard O/S
- services for talking to a serial port? One would hope so ... !
-

-
- Okay, that's a great start. Let's see, what you would need to serve as a UUCP
- site that sends/receives news is:
-
- 1) A working version of UUCP that allows both incoming and outgoing data
- 2) A working version of C-news
- 3) A newsreader, and
- 4) possibly an NNTP server (depending on the newsreader).
-
- It sounds like (3) is on it's way. (1) is on it's way as well, as long as it
- will work with smart serial hardware like the Digiboard and will allow
- bi-directional telephone calls. I have no idea about (4), but it may not
- be needed - does the rn port need an NNTP server? What about the shareware
- version of the Windows Newsreader?
-
- (2) sounds like the real wildcard here. Does anyone know about a port of
- C-news to Windows NT? Is anyone looking at it at all? If I don't hear
- anything here, then I'll probably send MAIL to the authors and ask in one
- of the news-related groups ...
-
- Any further information would be appreciated ...
-
- Thanks!
