There is one fairly pronounced caveat in what Jeff writes that I should add:
the version of telnet that is part and parcel of the DTC-based Telnet Access
Card is a very primitive implementation of telnet that doesn't support many of
the common (and sometimes required) features of telnet. More than that, it has
a few errors in its telnet implementation.

If you are currently using a DTC-based TAC card, I would immediately abandon
it for host-based telnet. The second question that people often ask about
their TAC cards is: "Can I upgrade it to current standards?" I'm sure that the
answer is no -- and will forever be no. In its day, the TAC card was a
relatively expensive cost item; host-based telnet is free. Given the
economics, I'm sure that no one will ever go back and upgrade the card.
