This tuple specifies the function of the device, in this case the tuple states the device
is a serial port.
This tuple is the function extension tuple, and provides more detailed information
about the function of the device, and provides the following information:
• Serial port includes a 16550 compatible UART.
• Space, Mark, Odd and Even parity
• 5, 6, 7, 8 bit chars
• 1, 1.5 and 2 stop bit operation.

The Level 1 version / product information tuple provides the host with the following
information:
• The device supports version 7.1 of the PC Card Specification.
• The Manufacturer String is “PC CARD”
• The Product String is “GENERIC”
• The Additional Product Information strings are empty.
The CISTPL_CONFIG tuple provides basic configuration information including the
following:
• Base address of the configuration registers (specified as 0xFA)
• Which configuration registers are present and supported (Configuration
Options Register, Configuration Status Register, Pin Replacement
Register, and Socket and Copy Register are supported).
• Index of the last Configuration Table Entry (set to 0x02).
0x1B
