846.0. "Big Endian/Little Endian" by 33836::MCMULLEN () Thu May 25 1989 21:52

    Has anyone noticed a big endian/little endian problem in the
    X protocol when using tcpip transport to other vendors workstations?
    It appears that we can't communicate to machines of different byte
    order than VAX architecture. I've seen it on a vms machine running
    the tcpip transport with the Connection software and been told it
    also occurs under Ultrix.
    
    Thanks in advance,
    Mike McMullen

	Ultrix servers and clients can talk to any other machine that has correctly implemented X, regardless of byte order, although some clients have problems with image bit order. It would be pretty useless if all we could talk X with was other Vaxen, or machines with the same byte order as Vaxen. Jeff
846.2	What about VMS?	RTPSWS::MCMULLEN		`Fri May 26 1989 16:54`	11
	True. I agree with every word you say. I didn't see the problem with Ultrix and I have had no problem with my own tinkering here at Digital and when I was working at NCSU. However I did see the problem on a VMS machine talking to another machine using the tcpip transport executable with the VMS/Ultrix Connection. Connections to that machine from other types of workstations worked fine. I was curious if anyone else had seen a problem when using tcp/ip transport from VMS. Mike
846.3	Known bug in VMS	19458::FISHER	Burns Fisher 381-1466, ZKO3-4/W23	`Tue May 30 1989 13:26`	5
	It's a known bug in VMS that the server can't service clients with other byte orders. Fixed soon, I hope. Burns
846.4	It's in there.	19763::MARRA	Acts 2:4	`Tue May 30 1989 15:12`	2
	Yeah, it's fixed in V2... I confirmed the fix last week.

846.6	Prophecy? Cynicism!	POOL::HALLYB	The Smart Money was on Goliath	`Wed May 31 1989 09:38`	4
	Now all we need is to discover that one layer of the protocol byte-swaps the data, unbeknownst to a lower layer that also decides it needs to byte-swap the data...
