According to the inet.conf file, inetd is trying to start tcpd. But I don't have an tcpd! Can somebody tell me where to get it from? Also for Alexis: the serial-FAQ is at sunsite.unc.edu in the pub/Linux/docs/faqs subdirectory. It's a great FAQ, but the thing that confuses me is that it says to disable all messages from the modem (E0 and Q1), but then the getty.xxx files say to use INIT="" ATZ\r OK If the messages are disabled, getty will never get the OK. Also, note that some of the later modems have 2 possible configurations that ATZ can reset to. You need to make the line ATZn.... I'm using one line as dial-in and dial-out. After much experimenting, I decided to us uugetty (from the getty_ps pacakge) and set my modem up to auto answer. So far I can dial in ok and I can dial out using Kermit. If you need more specific file configurations, e-mail me. Hope this helps and thanks to the guys for writing all of the documentation!

All SVGA cards that I know of provide full Herc backwards compatibility. And CGA, too. If the MiscOutReg is set to color mode, then the mono ports are disabled, and you can use a herc along with the SVGA. Similarly, if you set the MiscOutReg to mono mode, the SVGA can coexist with a CGA card. This is how the two-headed mono server works (the SVGA mono mode is actually 16-color mode, with only one bit-plane turned on). But the bottom line is that what he wants to do is impossible. Or at least a rediculous amount of work. The problem is that IBM, in its infinite wisdom, has the bit order backwards between the packed-pixel and bit-plane modes. An X server can't support two bit orders. So the only way to get things to work would be to swap all the bits around for one screen on the other. No, thanks.

Date: Mon, 23 Aug 1993 22:31:31 GMT I believe that /dev/tty is a pseudo device used to open any free tty (is this correct?). I have the same problem under Linux 99.PL10 on my laptop. The process works fine on my desktop unit though. The actual problem occurs on the open call (per ptrace) open("/dev/tty", RDONLY, 666) = -512 -512 is the error code ERESTARTSYS. I think that in this instance there is a problem with the locking mechanism between /dev/cuax and /dev/ttySx. Perhaps someone with more knowlege and a little free time might be able to explain the problem or fix it. In the meantime I suggest you replace the /dev/tty entry and use /dev/cua1 instead of ttyS1 as your tty for getty.

Date: Mon, 23 Aug 1993 23:49:28 GMT Has anyone out there in the wonderful world of the internet managed to configure a NetBlazer as a SLIP server for Linux? So far, I can get dip to connect at 14400bps, then the NetBlazer seems to send a stream of crap and then hangs up. I have made sure that my settings are 8n1 when dialing up, so I don't think it is anything as simple as a parity problem. Also, both ends are using Telebit T3000 modems, so I don't think that is a modem compatibility problem. My guess is that the NetBlazer is expecting another NetBlazer to dial up and is trying to send and initialization string, but I don't know how to tell it otherwise. If you have had any experience with NetBlazers let me know, I am *very* interested in getting this working soon. thanks scott ------------------------------ From: aajayk@sjoki.uta.fi (Jari Yli-Koivisto) Subject: X problem ATI chipset 38800-1 + SLS1.03 Date: Mon, 23 Aug 1993 08:42:37 GMT I have here In our school Olivetti M400-60 with OEM ATI Ultra (pro?) chipset is 38800-1.

I tried to recompile to remove all of the extra drivers. I hacked a fix for it--it seems that some of the ifdefs are munged in the fs Makefile.First, look in the Makefile in /usr/src/linux/fs. Look for: ifdef CONFIG_QUOTA FS_SUBDIRS := $(FS_SUBDIRS) quota endif Comment out the "ifdef" and "endif"--there's a routine in the quota subdirectory which must be defined whether quotas are used or not. Now go to /usr/src/linux/fs/quota and edit sys.c. At line 95, a dummy version of "sys_quotactl" is defined for use when quotasare off. The function definition is munged-- it should be extern "C" int sys_quotactl(int cmd,.... and NOT int sys_quotactl(int cmd,.... (see the declaration of the "real" function at line 39.) I think this is what the authors intended, and it gave me a working kernel without quotas. Sorry I couldn't provide a diff--I didn't bother to save the original files. (It's only 3 lines anyway).
