Tread softly, for you tread on
Rule #4.
I have to admit I generally avoid the use of co-processes due to their complexity and the convenient alternatives such as
expect (instead of co-processes) and
ssh (instead of
telnet). Any reason why you particularly need to use them here... a learning exercise? My
telnet on HP-UX doesn't seem to want to deal in stdin/stdout/stderr anyway, it seems to talk directly to my tty... I'll try elsewhere too.

telnetrc
telnetrc(4) Kernel Interfaces Manual telnetrc(4)
NAME
telnetrc, .telnetrc - Specifies setup commands for a telnet session
SYNOPSIS
$HOME/.telnetrc
DESCRIPTION
The .telnetrc file contains the setup information for a telnet session. It is a hidden file in your home directory and must be readable by
the user logging in.
The file can consist of multiple entries for each remote host to which a user can connect. A remote host entry consists of multiple lines.
The first line is the name of a remote host. The subsequent lines must begin with blank spaces, and contain telnet subcommands. These sub-
commands are processed as though they were typed in manually. Lines beginning with a number sign (#) are comment lines. See telnet(1) for
a complete list of telnet subcommands.
To specify subcommands that apply to all systems, create an entry, using the word "DEFAULT" as the system name, and specify the telnet sub-
commands in the subsequent lines.
EXAMPLES
The following shows a sample .telnetrc file:
# Beginning of telnetrc file # Default subcommands that apply to all systems DEFAULT
environ undefine USER # First system entry system1
set echo
toggle crlf # Second system entry system2
set echo
mode line
toggle crlf
FILES
User-customized telnet startup values.
