- Well, some of the Boca multi-i/o "dumb" cards are currently being tested
- by Ted T'so, I think.
-
- Boca's dumb cards all use quad versions of the 16550AFN chip. One of them
- is a BBIO2BY4, and has 2 parallel and 4 serial ports; others come with
- 4 serial expandable to 8; and they even have a 16-port dumb serial card.
-
- All relatively cheap, but the ones with a lot of ports do not have all
- the RS-232 lines enabled. You should check before purchasing.
-
- We have a few of the more useful data/spec sheets available here for
- mail-server request. The files have been scanned in as 300x300dpi
- TIFF images, then ZOO-compressed. (The mail-server will automatically
- uuencode them and send them to you as ~50kbyte messages.)
-
- To get a list of files, and the help file, send the following to:
-
- mail-server@questor.org
-
- ...and in the body of your text at the left margin, enter:
-
- help
- dir
-
- That should get you started.
