Your wodSSH is either misconfigured or badly written, I don't know wodSSH, but I do know OpenSSH.

In terms of OpenSSH, if I type:
ssh somehost
I will establish a login session with that host. I will have a pty and a login shell and everything will be fine. But ssh can be used in a second way. I can type:
ssh somehost uname -a
and ssh will connect to somehost, run the command "uname -a" and return the results. This type of connection is not interactive in nature and it will not have a pty.

To reproduce your problem, I can type:
ssh somehost ksh -i
This will run an interactive ksh on the remote host. However there will be no pty, no login shell, etc. This is a useful option. ptys are a limited resource. If a box is up for a long time, you can run out of pty's. When this happens, I will connect in a manner similiar to this and free some up. But other than that, I would never use this technique.

So your wodSSH is not establishing a login session for you. Instead, it executing a remote command that is "ksh -i". You're on your own there. I never heard of wodSSH before.

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
