Achieving High Baud Rates
Determining the Baud Rates
The following list provides ideas on how to achieve high baud rates with your
PC.
There are various third party COM Drivers on the market, which are
replacements for the standard driver that comes with the Microsoft Windows
operating system. These drivers are supposedly faster, but ICEPIC software
has not been tested with these drivers.
To determine the baud rate setting for your COM port, go to your DOS prompt
and enter mode.
If you have a newer system, the baud rate should be set to at least 1200.
To change your baud rate, see your Microsoft Windows documentation.
• Use an I/O Card with a 16550 processor.
• Older IBM
• Upgrade your Windows 3.1 to one of the new Windows operating sys-
• Upgrade you computer to at least 64 MB RAM.
• Remove any screen savers. These slow down your Windows operation.
Newer computers come with 16550 processors (especially notebook
computers). Unlike the 8250, the 16550 UARTs have a 16 byte FIFO
which improves the speed of communications. Microsoft Windows will
have enough time before servicing an interrupt.
tems. Even if your computer is not networked, the new Windows operat-
ing system’s serial port driver are significantly better.

PC compatibles were equipped standard with 8250 UART.
