Downloading problems with WiModem 232 and a UDS-10

You can NOT stack ATHx with any other command. The ATH1 is what matters here. The message is stored permanently so you can set it permanently by setting however you want then save it with AT&W. ATH0 or ATH1 are not a stored setting so you will have to issue ATH1 (by itself) to invoke this feature. Most BBS programs have a "off hook" or "maintenance mode" setting that would normally send ATH1. Back in the day, a caller would just get a busy signal until the BBS was put back online.

Glad you got this sorted out!
