We are using the Communications Tool Box and the Serial Tool for Serial Eudora. This is set up as 9600, 7bits, even, 1stop, Xon/Xoff. We are sending mail to an Apollo DN4000 running OS10.1. The latter is figured in tandem mode, so that if the data being sent (effectively outgoing mail) arrives too quickly, and the buffer fills up, XOFF is sent and XON when data can be resent. Without going into too many details, it looks like these XON/XOFF's (or some of them) are getting through the Serial Tool and to Eudora. Eudora is looking for a certain string sequence (\r\n<number>) and doesn't see it because XOFF/XON is sent between the newline and the number (this only occurs with a suitably big enough mail, and there might be 2min gap here). I know from an analyser that if no Xoff/Xon sequences occur, there is no problem, but if they do at critical times Eudora gets confused. Has anyone else had a similar problem, and especially anyone know of a patch/solution? I could stop the Xon/Xoff's occuring, but that would result in garbled mail! I've told Steve Dorner about this, but I would welcome any other suggestions. John Forrest Dept of Computation UMIST
