Hi,

I have a simple Expect script that starts as:

set timeout -1
spawn ftp a.b.c.d
match_max 100000
expect=A0 "*Name (a.b.c.d): "
send -- "anonymous\r"
expect=A0 "*Password:"
send -- "anonymous\r"

This is fine in Cygwin 1.5 on my PC (installed in Nov 2008)=A0yet on some o=
ther 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 th=
e first character but the rest of chars are echoed on a new line and the lo=
gin 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"
