Subject: tcgetattr fails in 2.4.3

ppp chat script stopped working under 2.4.3. I ran a program of my own
that opens ttyS1 and it also fails on a tcgetattr with errno=5 (IO error).
The ppp chat script and my program both work fine under 2.4.2 and older.

I noticed that, but then I noticed I'm using pppd 2.3.11, and
Documentation/Changes says I should use 2.4.0b1. Then again
Documentation/Changes said the same thing in kernel 2.4.2 as well, and
pppd 2.3.11 works fine there.

I am running pppd 2.4.0b4 so that should not be the problem. However if the
problem is related to tcgetattr bogus failure, then I do not think
pppd would be the problem especially since it is failing in chat.

Does anyone know under what conditions a errno=5 (IO error) should be
returned from tcgetattr(fd,&t) when fd is opened (rw).
