Faster baudrates for DL11-W

The DL11-W card is a general purpose serial interface for UNIBUS-PDP-11. It was introduced with the PDP-11/34. Since the card also contains a real time clock, it is often called "SLU/RTC".

The best documentation is on pdp-11.nl. (Go "Peripherals/comm/interfaces/DL11-W")

Here I show how you can speed up the card from 9600 baud to 19200 or 38400 ... with part for less than $5.
