X11R4 problem on AT&T Unix System V Release 3.2

[Karl Lovink]

Hello, Netlanders

I'am having some problems to get X11R4 running on a 386box with AT&T 
Unix System V Release 3.2 with a VGA screen attached.
The X11R4 has been patched up to level 14 and the vga server which
was posted several weeks ago in comp.sources.x is also included.
When I start X with xdm I get a error.
Spitting through the code I found the the open of the streams device
went wrong, e.g. /dev/pts000 is linked to /dev/X/server.0.

/usr/lib/X11/xdm/xdm-errors:

GetConnectionType(L)
Calling CallLocalServer(unix)
Found a vga with color display.
Server linked Mon Sep 24 21:18:22 EDT 1990 by root on jupiter 
X Window System protocol version 11, revision 0 (vendor release 4)
Using RT keyboard layout...
No reply from the server.
Cannot open /dev/X/server.0
XIO: Interrupted system call

The code where the streams device will be opened.

	if ((fd = open (ptmx, O_RDWR)) < 0) {
		close (server);
		PRMSG("Cannot open %s\n", ptmx, 0);
		return(-1);
	}
Questions:
1. what could cause this problem?

2. What does get connectiontype L means, is this correct?

Thanks in advance and kind regards,
