Several years ago my 1st Toshiba install was a CTX28. The LAN interface is an optional card in that system, and the company I worked for at that time did not buy it. I did the entire instal through a phone. It took a very long time, and some things could not be programmed with a 10 button phone.

Some time later, on this site, someone mentioned that the CTX-28 has a built-in modem and 1 analog port. You can use the analog port and the laptop's modem to connect to the system with Winadmin. It will be slower then a LAN connection, but faster then using a phone. (I've done the same thing with a voicemail when I did not have the correct cord)

Winadmin is only used for old systems, such as the CTX28. It will also work for CTX 100 or 670 running software 2.22 or lower. After 3.XX, you would want to use emanager. I have found that while emanager does work on older systems, it seems to be a bit buggy on very old software, like version 1.XX.
