        My guess for the solution to this problem would be to make sure that
your DTR (data terminal ready) and the DCD (data carrier detect) lines are both
asserted (high) when you issue the CTTY command.

        I used this command to kludge a "shell to DOS" command for a BBS I ran
for my old high school last year, and this command was only used during an
online session when both DTR and DCD were high (since someone was calling in). 
This seems to make sense because CTTY needs to make sure that things it sends
can actually go out the port (which is only possible when DTR is high).
