Message-ID: <1991Feb13.173931.38868@eagle.wesleyan.edu> Date: 13 Feb 91 22:39:31 GMT References: <653@twg.bc.ca> <3773.27b7e1b6@hayes.uucp> Organization: Wesleyan University Lines: 15 In article <653@twg.bc.ca>, bill@twg.bc.ca (Bill Irwin) asked about why he sometimes sees garbage on the screen when he logs off. That happens to me at times, too: when using plain vanilla 2400 to Wesleyan, which simply drops carrier after logout, I get such bursts of ASCII (once even the escape sequence for locking my keyboard!); on the other hand, using the same plain vanilla 2400 to AT&T Mail, the cutoff is spotlessly clean. From trying at 300, where I can distinguish mark from space by ear, I dicover that AT&T Mail sends a really long break after logout, and only then drops carrier -- that break is long enough to convince my modem of CARRIER LOST, and it hangs up cleanly. MNP-4 connections, like those to MCI Mail, have always been clean at logout. -- Fred
