Thank you, I'll try that.
In the meantime, I collected some more information while trying this with
ftp. Maybe this will help isolate the problem.
Some functions work when piping a subshell into an FTP session, but the
printf and echo fuctions do not work properly.
( sleep 2; printf "username"; sleep 2; printf "pwd" ) | ftp 10.0.0.24
This will connect to the FTP server, which will query for the username, then
afer a 2 second delay, apparently send a carriage return, delay again, and
get stuck waiting for a password. So sleep works, but the two printf's are
sent together as a single carriage return after the first delay.
( sleep 2; echo "username"; sleep 2; echo "pwd" ) | ftp 10.0.0.24
Same behavior as the printf method, except that a single carriage return is
sent BEFORE the initial 2 second delay. The sreen is shown waiting for a
password, like in the first example above.

# ( sleep 2; printf "username"; sleep 2; printf "pwd"; sleep 2 ) | ftp
10.0.0.24
Name (10.0.0.24): Password:

I couldn't get any function to work when piping a subshell into telnet.

Is there a way around this?
Try building netcat instead (the command is usually "nc").
It's more appropriate for this job, and should build easily.
