Ptys aren't just ptyp*; the full set of pty nodes consist of the
filenames pty[pqrsPQRS][0-9a-v]. The last character only goes to 'v'
because that gives an even power of 2 (32) combinations. 8*32 = 256
total devices.
If you don't see them in /dev, run "./MAKEDEV pty0 pty1 pty2 pty3 pty4 pty5
pty6 pty7", which will create all 256 device files.

(this is standard operating procedure on all the FreeBSD lists, BTW)
