Parallel Hotport
Gives the printer the ability to handle multiple data streams simultaneously.
It allows the printer to service hosts attached to the serial, parallel, and either
the coax or twinax ports as if they were the only interface connected.
Trickle Time
This functionality prevents an attached host from timing out. In order to
support this feature, the port has to be able to accept data from the host and
store it for future use. The selected value is the time that the printer waits
before getting the next byte of data from the host. Set the value to be less
than the host time out value. If the value is too much shorter, the printer fills
up its buffer too fast. This function is not applicable for C/T hotport.
Timeout
This is the value used by the printer to time out from the current port and
check the other ports for data to print. When the printer has not received data
from the host after a certain period of time, it needs to Timeout in order to
service the other ports.
Report Status
When this option is enabled, faults are reported even if the fault is not on the
current active port. If the option is disabled, a fault on the printer is reported
only if it occurs on the active port.
