5476.0. "Doubt about Lat behaviour !" by VAXRIO::16.179.32.123::Manoel () Tue May 27 1997 17:54

	Hi, folks

	I just want to know if it is supported or not !
	A customer using Ultrix V4.4 has prepared two queues in /etc/printcap,
and these queues are associated to different tty's, wich are mapped via LAT
to the same physical device, while "ct" equal LAT in both.
	I think it won't work fine once it can happen some problem with LAT 
while trying to control the flow of data beeing sent to the same physical 
device, that is a server port.
	Thanks in advance for any help.
	Regards.

5476.1	i don't think it will work	GIDDAY::STRAUSS	talking through my binoculars	`Tue May 27 1997 18:59`	11
	Hi Manoel I'm not certain, but I think it will not work. If two print jobs are queued to the same server port, I think tey will be mixed up together into one large, meaningless printout :-( If I had a terminal server, I would test it. Can you test it yourself? The results could be interesting. leon

	If these are two separate ttys, it'll work just fine. To the terminal server, it just looks like two system vying for the same port. The terminal server knows how to deal with that.

	And, even if it didn't, I think the lpd subsystem has provisions for two queues using a common lock file to control access to the same device. I've never tried this though.

	Ok, folks. In fact it is working, but sometimes one of the queues just stuck, with a status wainting for it to became ready. Then the customer has to stop and start the queue and it starts to work again. I'll talk to them that it is not supported. Thanks. Manoel F. Abreu Neto (MCS/DEC@Rio)
