Bo Zimmerman has uploaded a file in the Facebook group: GEOS - Wheels - GeoWorks - MegaPatch - gateWay.
Here is his description of the program --
1.3 of geoTelnet, a full color ANSI/ASCII Telnet client for C64Net WiFi internet modems (and compatibles). Also supports X-Modem transfers, and has a Phonebook. Works in GEOS 64, GEOS 128, Wheels 64, Wheels 128, MegaPatch 3.0 (64 and 128), and probably gateWay, all in 40 columns only.
Currently, the only way to download it is to be part of the above Facebook group and download from there.
