I picked up a cheap USB CF Reader off of Amazon to transfer files for to the Tandy 1000SX, and, aside from PKZIP and PKUNZIP, the first thing I threw on it was Telix. The good news, the 2400bps modem works fine, even over crappy Digital Home Phone from Spectrum. I found a dial-up BBS number, and it connected fine. I did get booted a couple of times, but I suspect this is because I forgot to disable call waiting first, so I've disabled it completely for my service rather than use *70, on each call, as I don't use that line for anything else.
The bad news, did we really do any work this slowly? It took about 2 hours to install Telix. I guess multitasking back then meant starting your install and then doing the dishes and laundry while you waited ;)
