C - Reserved
Channel
As previously discussed, it is possible for a station to send a message through the
MultiPro platform to another station. If the network administrator does not want a
particular device to receive these messages, this option may be turned on as shown
in Figure 10-6. If the MultiPro SEND function is going to be used, it is wise to
turn on this option for printers.
D - Device Is
Shareable
This option allows unattended sharing of a device, such as a remote printer, by
multiple hosts. The MultiPro platform automatically creates a logical pathway
from the host port to the printer’s terminal port when a host has something to send.
This implies that the host port initiates the connection to the terminal. Therefore,
the terminal does not have a default host or the Auto Connect option turned on.
The sequence of events is shown in Figure 10-7.
This leaves the printer in a state where it has no logical connection. The next host
that selects this device causes the sequence to start over, allowing completely
unattended sharing of a remote printer.
