We have always had a fairly high dialup failure rate. Finally I decided to investigate and put extra checks in the hysopn() routine. I discovered that under certain conditions the read of the Hayes result byte fails with an error 5 (EIO). This seems to happen most often after the previous dialup in the uucico loop got a busy line or other failure. The dial command write immediately before the read works perfectly. All subsequent dialing operations in the same invocation of uucico also fail for the same reason (but the writes always work damnit). I am continuing to investigate. In the meantime has anyone else seen anything like this? -- From the TARDIS of Mark Callow msc@qubix.UUCP, decwrl!qubix!msc@Berkeley.ARPA ...{decvax,ucbvax,ihnp4}!decwrl!qubix!msc, ...{ittvax,amd70}!qubix!msc "I'm a citizen of the Universe, and a gentleman to boot!"
