as others suggested, first increase the pseudo-tty number and create more
devices. however, when creating devices be sure to do them consecutively.
if you are missing any in the series, telnetd will stop searching at the
last consecutive one.

in other words, if you have /dev/ptyp* and /dev/ptyr* but you are missing
/dev/ptyq*, you will only be able to use /dev/ptyp*.

HTH, HAND.
