NOEPP mode can be selected with a check box under
Windows 95.
UNIDIR This option turns off backpack testing and usage of
bidirectional parallel ports. If the parallel port chip in your
computer cannot properly transfer data in bidirectional mode,
it may be necessary to force the backpack into unidirectional
operation on that computer’s parallel port.
Unidirectional mode can be selected with a check box under
Windows 95.
T1=xx Values of 1 to 25 are valid for this parameter. This option will
place additional signal speed delays on the backpack CD-
ROM when sending data into the computer’s parallel port. If
the computer’s parallel port is not capable of transferring data
at the speed calculated by the backpack device driver during
boot, this addition of timing delays may be necessary. The
higher the value, the more timing delays are added.
T2=xx Values of 1 to 25 are valid for this parameter. This option will
place additional signal speed delays when receiving data from
the computer’s parallel port.
T8=x Values of 1, 2 or 3 are valid for this parameter. This option
adds additional EPP signal speed delays on the backpack
CD-ROM when sending data on an Enhanced Parallel Port. If
the computer has an EPP port, but the port is not capable of
transferring data at the optimum EPP speed, additional signal
delays may be necessary.
