10 * It'd be nice if someone built a serial card with a 24.576 MHz
11 * clock, since the 16550A is capable of handling a top speed of 1.5
12 * megabits/second; but this requires the faster clock.

35 * The following define the access methods for the HUB6 card. All
36 * access is through two ports for all 24 possible chips. The card is
37 * selected through the high 2 bits, the port on that card with the
38 * "middle" 3 bits, and the register on that port with the bottom
41 * While the access port and interrupt is configurable, the default
42 * port locations are 0x302 for the port control register, and 0x303
43 * for the data read/write register. Normally, the interrupt is at irq3
44 * but can be anything from 3 to 7 inclusive. Note that using 3 will
45 * require disabling com2.
