Queuing With The Rtel Software - Black Box LE3700A-R2 Manual

queue_name
rprint1
/dev/ttyq1
/dev/ttyq6
The second line will request a connection to EPS "eps2" and service
"mod_srvc", using pseudo-device ttyq1. No password will be specified, and
queueing will be enabled. The third line will attempt a connection from
device ttyq6 directly to port 4 on "eps2," bypassing the service name syntax.
Running
% rteld -s
in this case would be the same as
% rteld -d/dev/ttyq1 -cmod_srvc@ets2 -q
% rteld -d/dev/ttyq6 -c:4@ets2 -q
You can use the 3 different configuration lines (for both printer and device
setups) in the same server_hosts file. You do not need any special handling or
ordering.
Once the EPS starts the rteld process, you should be able to use the pseudo-
device as any other physical device on the host. The EPS can echo files to it,
dump applications programs output to it, etc.
Two other rteld options provide information and a means of removing the
rteld process for a particular tty pair. The -r option will display the rteld
devices in use and their destinations. The -k option will remove the RTEL
handler for a particular device, or for all devices if the "all" is specified as the
device name. See the supplied rteld man page for a complete list and
description of the rteld options.
7.9 Queueing with the RTEL Software
You can queue a job in two places— in the host's print system (lp or lpr, etc)
or in the EPS itself. If you are only printing to one queue from one host to
one EPS service, the host provides the queueing, since it will not release a new
job to the EPS until the previous job completes. The second case occurs
when multiple print queues (possibly on more than one host) point to the
same EPS queue. In this case, the hosts will provide local queueing, but you
may still have multiple jobs attempting to access the EPS. In this case, the EPS
will provide queueing among the hosts. Jobs from multiple hosts are handled
in order, without regard to size or any priority, so if a particular host's queue
seems to stop for an extended time, this may be an explanation. The SHOW
QUEUE display on the EPS will show the order of jobs pending on the EPS—
you must use the host's lp or lpr utilities to show jobs queued by the host.
