The 25-pin parallel portislocated on the back of your computer. This port allows either normal or extended data transfer:

• Normal (one-way). The computer uses the port only to send output to

the parallel device. The computer does not receive input through the port.

• Extended (two-way). The computer uses the port both to send output

to the parallel device and to receive input from the device.

MS·DOS can use either normal or extended transfer. Other operating tems, such as OS/2, use normal transfer only.

The SetupTL3 Utility lets you control the data transfer mode of the parallel
