Internal ISA
IRC must be able to access the communications device, regardless of the state or health of the server operating system. If the managed server is unable to load the operating system, IRC is unable to access the communications device. In addition, the operating system may readjust the modem resources at

“Windows” Modems
Since these modems require the operating system and a proprietary driver to function correctly, they cannot be used with IRC. “Windows” modems, offered by some modem manufacturers, attempt to reduce the hardware complexity and cost of internal modems by replacing the industry standard controller interface with a proprietary one. Functions that would normally be performed on the modem in hardware are shifted to the main CPU. These modems require a specific driver and considerable CPU resources to function correctly. These modems are usually a poor choice in a server environment.
“Windows” modems were not designed to be accessible from anywhere except through the operating system. As mentioned above, IRC must be able to access the communications device regardless of the state or health of the server operating system.
