How do I remove information about PCMCIA two-port or four-port
serial cards from the Device Manager?
Because the two-port PCMCIA cards are single physical devices that
support multiple ports, they are registered as “multi-function adapters”
in the Device Manager. Each port is a child device listed under Ports
(COM & LPT). Windows Me/9x does not allow multi-function child
devices to be removed directly within the Device Manager. You must open
the Multi-function adapters class as shown in FigureC-2, select your
interface, and click on the Remove button.
What is the maximum baud rate supported and how can I set it?
The maximum baud rate supported is 460.8 Kbaud for RS-485 and
115.2 Kbaud for RS-232. To set the baud rate, use the SetCommState
Win32 function and pass the actual value of the baud rate in the BaudRate
field of the DCB structure.
