Description hjl 2001-11-15 20:02:17 EST
I can't log in from a serial port under kernel 2.4.9-12. It used
to work fine. zsh blocks at

open("/dev/ttyS0", O_RDWR|O_NOCTTY)

Can you see if using zsh as shipped with Red Hat Linux 7.2 helps?
Comment 3 hjl 2001-11-16 11:31:19 EST
I did try zsh from RedHat 7.2. It has the same problem.
Comment 4 Trond Eivind Glomsrxd 2001-11-16 14:31:10 EST
The one from rawhide? (4.0.4)
Comment 5 hjl 2001-11-16 14:46:10 EST
The same.

# rpm -q zsh
zsh-4.0.4-1
# strace -p 20994
open("/dev/ttyS0", O_RDWR|O_NOCTTY|O_LARGEFILE

zsh in RedHat 7.3 has the same problem. I am uploading a patch.
