Cc: freebsd-hackers@FreeBSD.ORG X-Sun-Charset: US-ASCII Sender: owner-freebsd-isp@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk Does anyone know (off the top of their heads) or experienced problems with modem transmissions as follows: /kernel: sio3: 8 more tty-level buffer overflows - traffic consists of mail is being sent between a FBSD box and a NT box (using exchange :>) on a permanent dialup line. Mail is queued at the FBSD side, and then relayed on. Both boxes have the same internal modems. I'm GUESSING that the modem is being flooded because too much mail is being de-queued on to it at once ?? so I've made the queue time smaller to try and stop the build up - but I'm a little perplexed as to why FBSD buffering does not seem to be working here ... or are the modems I'm using (latest Banksia) rubbish ?? Does anybody know if this is in fact the case ? what the root cause of it is and how to fix it ? thanks in advance REGS Stephen
