Downloading problems with WiModem 232 and a UDS-10

[DarkLord]

I compared my WiModem 232 settings to Amis's.

Identical except for:

Baud rate - 19.2 vs 9600. That shouldn't make any difference.

D0 vs D1 - inverts DCD polarity. I tried both ways. Didn't make any difference.

X0 vs X1 - just shows the connect speed when you logon. Again, shouldn't make
any difference.

I looked through my router (it's a Linksys) but I can't see anything that would make
any difference or would be affecting this.

Besides, if it was, wouldn't it also affect when I download using SyncTerm on my Windows
10 box or Kubuntu Linux laptop since they are also on the same LAN with the same
router and they download fine?

I also tried doing this:

ATDT*T0,darkforce-bbs.dyndns.org:520

ATDT*T0,192.168.X.XXX:520

Shouldn't the first take it out of the LAN and back in again?

Both connect fine btw, but neither will download successfully.

Thanks.
