redirect incoming telnet to com port

[saeedeh motlagh]

hello everybody

i have freebsd8.2.  i want to redirect incoming telnet from telnet port to
a com port. i mean if somebody telnet to my system with a specific port (or
22 which is default telnet port), connect to com port and can talk to modem
(something like cisco).

is it possible or not?

any hints or comments are really appreciated.
