Hi,
I have a simple Expect script that starts as:
set timeout -1
spawn ftp a.b.c.d
match_max 100000
expect "*Name (a.b.c.d): "
send -- "anonymous\r"
expect "*Password:"
send -- "anonymous\r"
This is fine in Cygwin 1.5 on my PC (installed in Nov 2008) yet on some other
PCs where I installed, last week, Cygwin 1.7 it fails at the Password
introduction. I tried more combinations of stty echo and/or raw but without
success.
Either it hangs without prompting the "Password:" or it prompts and gets the
first character but the rest of chars are echoed on a new line and the login
fails.
Thank you very much!
Bogdan Nicolau
PS
A short sample of my setup-for working PC- is here:
bash: cd: [~]$: No such file or directory
[~]$ cd "C:\backup\LaptopTools\ExpectWinUnix\expect-5.44.1\example"
[/cygdrive/c/backup/LaptopTools/ExpectWinUnix/expect-5.44.1/example]$ strace
ftp a.b.c.d
