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

53 * The following define the access methods for the HUB6 card. All
54 * access is through two ports for all 24 possible chips. The card is
55 * selected through the high 2 bits, the port on that card with the
56 * "middle" 3 bits, and the register on that port with the bottom
59 * While the access port and interrupt is configurable, the default
60 * port locations are 0x302 for the port control register, and 0x303
61 * for the data read/write register. Normally, the interrupt is at irq3
62 * but can be anything from 3 to 7 inclusive. Note that using 3 will
63 * require disabling com2.
