I think telnet requires .telnetrc for the initial handshake.
There might be man pages, try
For scripting ssh is better than telnet. An example:
At first it prompts for a password.
Create a ssh key with ssh-keygen on the remote side, and copy the public key in ~/.ssh/ to the calling side, then it won't prompt for a password.
The full login might complain about a not-working tty. For script-only access it is preferrable to invoke a shell command on the remote side:

bb-services
BB-SERVICES(5) File Formats Manual BB-SERVICES(5)NAME
bb-services - Configuration of TCP network services
SYNOPSIS
$BBHOME/etc/bb-services
DESCRIPTION
bb-services contains definitions of how bbtest-net(1) should test a TCP-based network service (i.e. all common network services except HTTP
and DNS). For each service, a simple dialogue can be defined to check that the service is functioning normally, and optional flags deter-
mine if the service has e.g. a banner or requires SSL- or telnet-style handshaking to be tested.
FILE FORMAT
bb-services is a text file. A simple service definition for the SMTP service would be this:
[smtp]
send "mail
quit
"
expect "220"
options banner
This defines a service called "smtp". When the connection is first established, bbtest-net will send the string "mail
quit
" to the
service. It will then expect a response beginning with "220". Any data returned by the service (a so-called "banner") will be recorded and
included in the status message.
The full set of commands available for the bb-services file are:
[NAME] Define the name of the TCP service, which will also be the column-name in the resulting display on the test status. If multiple
tests share a common definition (e.g. ssh, ssh1 and ssh2 are tested identically), you may list these in a single "[ssh|ssh1|ssh2]"
definition, separating each service-name with a pipe-sign.
send STRING
expect STRING
Defines the strings to send to the service after a connection is established, and the response that is expected. Either of these may
be omitted, in which case bbtest-net(1) will simply not send any data, or match a response against anything.
The send- and expect-strings use standard escaping for non-printable characters. "
" represents a carriage-return (ASCII 13), "
"
represents a line-feed (ASCII 10), " " represents a TAB (ASCII 8). Binary data is input as "xNN" with NN being the hexadecimal
value of the byte.
port NUMBER
Define the default TCP port-number for this service. If no portnumber is defined, bbtest-net(1) will attempt to lookup the portnum-
ber in the standard /etc/services file.
options option1[,option2][,option3]
Defines test options. The possible options are
banner - include received data in the status message
ssl - service uses SSL so perform an SSL handshake
telnet - service is telnet, so exchange telnet options
