- My serial port board has one socket, and one soldered-in 8250. I
- didn't want to use the socket, because that means buying the line
- drivers and external DB-25. I don't have the equipment for
- desoldering a 40-pin IC. Wire-wicking the solder off each pin, while
- an impressive feat, gets old fast. So, I got out the trusty dikes,
- and clipped off the pins of the 8250, and discarded it. I didn't
- desolder the pins even though it would have been easy at that point.
- I just put my shiny new 16550AFN over the remaining 8250 pins and
- soldered them together.
-
- Worked like a charm. Now I can communicate at 57600 baud without
- dropped characters!
