To those of you who have Lantronix UDS-10's and have been having problems downloading from Heatwave BBS lately, Kyle figured out the problem.
The problem started right after Heatwave switched from port 23 to 9640 to stop hacking attempts made by bots to the nearly universal port 23. Anyway, most UDS-10 users use the odd default port of 10001. Well, for some unknown reason, (one I would like to understand), the two non-standard ports of 10001 and 9640 do not play well together.
The easy solution/fix is to just change your UDS-10 to port 23 and the downloads will start working again.
