Bug 50142

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 4.01; Windows 98)

Description of problem:
When I redirect input and ouput in a bash shell to communicate with a 
modem on ttySx the output goes to stdout. 

It did work in RH5.1 but since upgrading to RH 7.0 it no longer works.

When using bash from the RH 5.1 distribution in an RH 7.0 environment the 
problem does not occur.

How reproducible:
Always

Steps to Reproduce:
1. Create a bash script such as;
_____________________
#!/bin/bash

chat -t 30 '' ATZ OK '' <> /dev/ttyS0
_____________________

2. Execute the scrpit

3. The output will be something like;
# ./"script_name"
ATZ

^C
4. Notice that the output from the chat command came to stdout instead of 
/dev/ttyS0
