Your port numbers are most likely #0 - #7 ... eight ports in all.  The /dev/tty??'s should tell you.

I regularly use minicom to dial out with the modem.  If you can't dial out, you are not going to get in.

When the kernel creates a ppp device, it keeps it re-using as necessary.  You can interpret the ppp0 - ppp6 to mean the kernel create 7 devices ..., a small leap (and not accurate) to say all 7 were in use at the same time.

I have had more pppX devices than the number of ports.  They were caused by sudden modem disconnects and early 2.4.x kernel code.   There was no real problem because of it.
