Personally, I do not recommend using modem access, as described above, because of some pertinent considerations. First of all, it's not secure--all data will be transferd via phone lines without any encryption (plain-text). Second, it's not suitable--you can only open one terminal per session. If you will need to gain access to a text console via modem, I suggest you to configure mgetty in AutoPPP modem. If using a PPP connection (like a dialup connection to an ISP) you can run the TCP/IP protocol and work with that.

For detailed information about ssh configuration in this mode, you will need to read the corresponding equipment manuals and HOW-TOs.
Solid state disks (SSDs) made a splash in consumer technology, and now the technology has its eyes on the enterprise storage market. Download this eBook to see what SSDs can do for your infrastructure and review the pros and cons of this potentially game-changing storage technology.
