SYMPTOM POSSIBLE REMEDY
• The driver might be set to hardware
flow control and the external cable may
not be wired correctly. Switch to
software flow control. If the problem
stops, then the cable is wired incorrectly,
not allowing the external device to
supply the necessary control signals.
• Make sure that hardware flow control is
set in your system.
• Make sure the attached serial device is
set to hardware flow control.
• Ensure the device is connected properly.
Most EPP devices have two DB-25
connectors labelled “COMPUTER” and
“PRINTER”. The first device should be
connected to the DB-25 labelled
“COMPUTER”. The next device(s)
should be connected to the DB-25
connector labelled “PRINTER” on the
first device.
• If a printer is required, it should be
connected to the DB-25 connector
labelled “PRINTER” on the last device.
• Ensure that the driver for each device is
installed and configured correctly. Note:
the driver for each device is supplied by
the vendor of that device.
• Make sure that the ECP printer port has
an IRQ assigned for EPP mode, or both
an IRQ and DMA for ECP mode.
