Many messages may be truncated. I normally saw several "N"'s in a row when I debug this last November. That meant that several messages starting with "November" were truncated to "N". ttymsg() checks the result of writev() and is more careful if writev() returns EWOULDBLOCK, but for non-synchronous ttys like serial ttys, writev() normally just buffers the data and it takes a tcdrain() to ensure that the data has at least been transmitted. Unfortunately, there is no way to determine if the data has been transmitted without blocking, and ttymsg() doesn't want to block. ttymsg() compounds the error by using non-blocking mode in most cases. When non-blocking mode is in effect at last-close time, it tells close() to discard the data instead of blocking. The last-close sometimes occurs in exit() when blocking in it is very inconvenient because it gives an unkillable (half dead already) process. When writev() returns EWOULDBLOCK, ttymsg() switches to blocking mode and can generate a horde of blocked or unkillable children. I don't know exactly what causes the b_to_q message. It is most likely a race in close. You can first-open tty's that are blocked in last-close, and having this open succeed is very important for unblocking the close usi9ng "comcontrol /dev/foo drainwait ", but the tty system doesn't seem to do nearly enough to handle races here.

The -current cu is a crock of tip. One of the bugs in it is that "cu -l /dev/foo" doesn't use the default line speed for /dev/foo; it enforces 9600. This is bug for bug compatible with the V7 cu except for the unusably slow speed of 9600. For perfect brokenness, the default speed should be 300.

Re: Serial break into debugger broken from 'cu' on -CURRENT?
serial break is different.. it is suppoesed to break into the d debugger if it receives a "BREAK" (i.e framing error) in the serial port. cu ,tip and other such programs have an escape sequence to "send a break" julian On Sun, 10 Mar 2002, Glenn Gombert wrote: > I just rebuilt -current on two development machines I use here at home, the > serial break "contol-alt-escape" appears to work fine on a stand-alone vox. > > > >(1) Is serial break currently broken in -CURRENT > > If I do a 'tip com1' from one box to the other and then do an > 'control-alt-escape' it breaks into ddd just fine as well : > > >(2) Is serial break currently broken in 'cu'? > > > > Glenn Gombert > [EMAIL PROTECTED] > > > To Unsubscribe: send mail to [EMAIL PROTECTED] > with "unsubscribe freebsd-current" in the body of the message > To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

My testbox (NoName) doesn't even react on halt. But in the normal case a serial break just does what it should do. Serial client is tip from 4.3-20010630-STABLE. My notebook is running -current from 15th feb and tip's break also worked always fine. Well sending the break sequence against an ssh or not after a linebreak are typical mistakes in usage. -- B.Walter COSMO-Project http://www.cosmo-project.de [EMAIL PROTECTED] Usergroup [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Actually, you need to look at where the error message is generated, which will tell you that it's running out of the things returned by "witness_get". Then increase the compile time constant that controls them, and you won't run out any more. In theory, the only thing that will suffer from this is that some things will not be "witnessed" correctly, which means that you could have any of the problems witness ordinarily catches for you, but not know about them. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

What I have observed is: I use the same gdb for remote serial debugging both for FreeBSD and Linux (ia32). That's right, it's a FreeBSD box running FreeBSD gdb in both cases. I can break to the Linux kernel, but not to the FreeBSD kernel. From this, I conclude that it's a kernel issue, not a gdb issue.

The break signal is "At least 250ms of marking space" (line silence), according to the Bell 103C and 212A and B standards. There are two ways that UNIX programs try to do this; the first is an ioctl() for "send a break"; the second is to set the baud rate to 0, and then set it back after a sufficient time. You should check to see if both approaches (the working one and the non-working one) are trying to use the same approach, or not. If they aren't, it could be something as simple as the number of loops before the baud rate is set back is wrong for your clock speed, and the loops should be replaced with a call to nanosleep. 8-). -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

It could be that the DS10 was sufficiently catatonic to not react to a break (how likely is that in the first place? I was looking at a hard lockup). Now that I followed Drew's suggestion to I suggest reverting rev 1.61 of alpha/alpha/interrupt.c (eg, disable interrupt thread preemption). I'm on the west coast right now, away from my alphas, but I had several buildworlds complete last week with ithread preemption disabled. Drew I have not seen a lockup anymore. I also had to take out options SMP in order to get the kernel link.

I've been unable to send break using -current cu to some Cisco's which I had to configure recently. Ecu from ports did work however. As I was -stable user some weeks ago I know that cu in -stable did work. The other thing I noticed was that -current cu handles speed switch differently, e.g.: stable: cu -l /dev/cuaa1 -9600 works well current: cu -l /dev/cuaa1 -9600 will connect to cuaa0 not cuaa1.. -s 9600 will work however. What I recall is that some time back uucp was shaken out of base system and cu also, cu's functionality was folded back to tip. Stable indeed has different tip and cu binaries, in -current there's hard link. -- Vallo Kallaste [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Serial break into debugger broken from 'cu' on -CURRENT?
For the past couple of months, I've been working with a set of identical test boxes from SGI which, for some reason, stopped responding to serial break on the serial console. I switched to the 'alternative break' option in LINT, and things work fine. I assumed it was actually some issue with that particular batch of machines, since no one else had had a problem, and I didn't really have time to follow up. Yesterday, I brought online two more crash boxes via serial console, both older TeleNet servers, and noticed that neither of them respond to serial break over the serial console using cu. This leads me to wonder two things: (1) Is serial break currently broken in -CURRENT (2) Is serial break currently broken in 'cu'? I have't had a chance to follow up on either, but was wondering if anyone else had experienced this? Essentially, hitting ~# in cu no longer results in boxes dropping to the debugger. Enabling the alternative break and using ~^B works fine, and Ctrl-Alt-Escape works fine on the real console.
