1.11.5 Parallel port performance and reliability
We are aware of several problems with parallel port behavior when working with
built-in parallel ports on PC platforms — where the hardware implementation and
supported modes of operation have changed greatly over the development history of
the PC.
For built-in parallel ports, there are different issues under Windows NT as opposed to
Windows ME, Windows 98 and Windows 2000.
Windows NT
Under Windows NT, the data transfer rate of some parallel ports can be very
poor. In most cases, the data rate achieved by the RIP is now as high as can be
achieved by copying a file to the parallel port, but this rate is often less than you
may expect to achieve. (Windows NT always uses the parallel port in a basic or
compatible mode, regardless of BIOS settings such as those discussed next.)
Windows ME/Windows 98/Windows 2000
Under Windows ME, Windows 98, and Windows 2000, the parallel port driver
can achieve higher data rates, especially when operated in ECP mode. Using
this mode the operating system sometimes crashes or shuts itself down. You can
avoid these problems by reconfiguring the parallel port in the BIOS to select the
most basic configuration. The way to enter and change the BIOS configuration
varies from machine to machine, as does the terminology used for the parallel
port mode.
To avoid crashes, try using options with descriptions such as "bidirectional". Do
not choose any option where the description includes the words ECP or EPP.
1.11.6 Problems with passwords
If you have problems enabling a device or option you should confirm with your sup-
plier the password or password file. They may provide you with a new password or
password file. If this is the case, you may need to provide the serial number of your
RIP. The RIP displays this number in the RIP monitor window when starting up, in the
form:
Serial number: 1234-56
