The devc-pty manager is a small pseudo-tty manager for
QNX Neutrino. It can support up to 256 ptys, using the naming scheme:
- pty[p-zP-T][0-9a-f] for the master device
- tty[p-zP-T][0-9a-f] for the slave device
The master and slave device pair share the same letter and hexadecimal digit.
Start devc-pty with 32 ptys:
devc-pty -n 32 &
