Well, are you sure that mgetty 0.13 is running? In older versions, this was common (well... that's what you get if you use unbuffered one-byte read()s for ease of implementing), but in 0.13 the fax reception stuff has been changed to use buffered read()s. With the old unbuffered reads, it was very likely that data is lost, but with 0.13, I have tried receiving a five-page fax while the system load was at 5 (!) - and no lost any data at all (on a 386/40). Does your port use a 16550? Which port speed do you use for fax reception? >I seem to have noticed that even during >the fax receive, OPOST and OCRNL are active; is it quite OK? That will not do any harm, since only the direction *to* the modem is postprocessed by the serial driver. One problem *may* be that you use a fairly old linux version, I think in the serial driver had been a lot changes since then, improving reliability at high speeds. gert -- ... ich kann diese signature nicht mehr sehen!

The seg fault happens in unix_get_info (from memory). The reason Im concerned is that Im trying to modify the ftpd-diku sources to work over a term connection. It works fine, except that exenually (sooner or later) the 'connect' system call in terms 'open_unix' function catches a SIGCHLD, gets interrupted and the program segfaults. Under pl13 it takes lonmger for this to happen, but it still does. ok heres a little scenario for you: before: netstat -x works fine from remote I ftp into my tredired box do a few dirs, then after about 5 or 6 -"425 remote server has closed connection" debugging output from ftpd: socket(PF_UNIX, STREAM, 0) = 13 connect(13, AF_UNIX(//.term/socket), 16) = -1 (Interrupted system call) - [SIGCHLD] write(12, "connect 4 Interrupted system cal".., 34) = 34 close(13) = 0 - [SIGSEGV] + [SIGSEGV] result from netstat -x now ahh.. well it erm still works at the moment ... hmm ANYHOW - does anyone have any ideas what the SIGCHLD is doing and why it causes that bit of code to seg fault? also - if I put a loop around the connect, so that if it fails, it tries again, it just loops indefinately, trying. any help that anyone has to offer is muchly appreciated... -- c9108932@cs.newcastle.edu.au - Simon Ferrett Due to technical difficuties, we are unable to bring you your regularly scheduled .signature - normal transmission will resume as soon as possible... ------------------------------ From: iiitac@swan.pyr (Alan Cox) Subject: Re: Port respawning too fast Date: Thu, 16 Sep 1993 08:10:20 GMT In article c9108932@peach.newcastle.edu.au (Simon J Ferrett) writes: >levinson@vax.sonoma.edu writes: >>I can log on, work, then log off, however on my consople I get the message: >>Respawning too fast.

Dir may have the value PLUS for a limit from above, MINUS for a limit from below, or may be omitted (implying a two-sided limit is to be computed). For the method see Wang, P., "Evaluation of Definite Integrals by Symbolic Manipulation" - Ph.D. Thesis - MAC TR-92 October 1971. LIMIT uses the following special symbols: INF (positive infinity) and MINF (negative infinity). On output it may also use UND (undefined), IND (indefinite but bounded) and INFINITY (complex infinity). LHOSPITALLIM[4] is the maximum number of times L'Hospital's rule is used in LIMIT. This prevents infinite looping in cases like LIMIT(COT(X)/CSC(X),X,0). TLIMSWITCH[FALSE] when true will cause the limit package to use Taylor series when possible. LIMSUBST[FALSE] prevents LIMIT from attempting substitutions on unknown forms. This is to avoid bugs like LIMIT(F(N)/F(N+1),N,INF); giving 1. Setting LIMSUBST to TRUE will allow such substitutions. --More-- Since LIMIT is often called upon to simplify constant expressions, for example, INF-1, LIMIT may be used in such cases with only one argument, e.g. LIMIT(INF-1); Do EXAMPLE(LIMIT); for examples. (D7) DONE (C8) limit(sin(x)/x,x,0); (D8) 1 This even shows how you can get on-line help, using describe();.
