When set to disable, the printer does not process data

from the Serial port while OFFLINE.
When set to enable, the printer continues to process
Enable (but not print) the current job from the Serial port while
the printer is OFFLINE until the printer's buffer is full.
Factory Default Disable
Host IO > Serial Port > Report Status
When a fault condition occurs in the printer, normally only the active port
reports the fault to the host. With this menu item enabled, this port will report
any fault even when it is not the current, active port. This submenu is only
available when Host IO > Control > Interface is set to Auto Switching.
Disable Will not report the fault unless the active host.
Enable Will report the fault even if not the active host.
Factory Default Disable
Host IO > Serial Port > Trickle Time
When the printer is printing data from a host and a second print job is
received by the printer from a different host, Trickle Time prevents the
second host from timing out while it is waiting for its data to be printed. In
order to support this feature, the port has to be able to accept data from the
host and store it for future use.
For example, if the printer is printing a job from the serial port, and then
receives a second print job from the parallel port, the data from the parallel
port will "trickle" bit by bit into the printer buffer to prevent a timeout error
from being sent back to the host connected to the parallel port.
The selected value is the time that the printer waits before getting the next
byte of data from the host. The Trickle Time value should be less than the
host time out value, but not too much shorter or else the printer fills up its
buffer too fast.
This submenu is only available when Host IO > Control > Interface is set to
Auto Switching..
Options ¼, ½, 1, 2, 4, 8, and 16 seconds
Off Disable trickling of data.
Factory Default ¼ second
