Description:

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.

Examples:

Start devc-pty with 32 ptys:

devc-pty -n 32 &
