I've noticed a change in behavior which ocurred when I upgraded from 7.1-STABLE compiled 2/8/2009 to 7.2-PRERELEASE compiled 4/24/2009. The change is that the system can't display full screens in the Cygwin window. The screen gets filled slowly, with long pauses between successive partial fills. This seems to only occur when I'm logged in from work using Cygwin SSH over the Internet to my home box; the final link is via Comcast, if that makes a difference. Connecting from witnin my local network, also using Cygwin SSH, no such problem. Rebooting the old kernel solves the problem. The work PC is running Cygwin OpenSSH 5.1p1/OpenSSL 0.9.8j (7 Jan 2009); the home PC is running Cygwin OpenSSH 5.1p1/OpenSSL 0.9.8i (9/15/2008). The results of "stty -a" under new and old kernels yeilds exactly the same thing: speed 38400 baud; 90 rows; 80 columns; lflags: icanon isig iexten echo echoe -echok echoke -echonl echoctl -echoprt -altwerase -noflsh -tostop -flusho pendin -nokerninfo -extproc iflags: -istrip icrnl -inlcr -igncr ixon ixoff -ixany -imaxbel -ignbrk brkint -inpck -ignpar -parmrk oflags: opost onlcr -ocrnl -oxtabs -onocr -onlret cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow -dtrflow -mdmbuf cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = ; eol2 = ; erase = ^H; erase2 = ^H; intr = ^C; kill = ^U; lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W; Mike Squires mikes@siralan.org
