Casper Dik, & firstname.lastname@example.org gave me the correct answer. Thanx to others
I do not need to increase nptys anyways.
You *CANNOT* increase the number of ptys without rebooting.
Here's why: when the system boots, an array of size pt_cnt *
is allocated; all structures in the array are initialized.
If you change pt_cnt when teh system is up, the amount of allocated memory
not increase. When you allocated the next pty, the system will use memory
beyond the amount actually allocated; data corruption will occur. The
will eventually panic.
