- A change in the rom code in version 1.300-07 addresses this issue
- already. By setting S192 bit 3 you enable your modem to support short TRN
- sequences. This resolves the problem connecting to some of the Multitechs
- where using the longer TRN sequence fails. MultiTech has since release
- rom updates that resolve this issue as well.
-
- You may want to get a current copy of our v34_list.txt file which details
- all of the commands (including the S192 settings) that your Supra modem
- supports. Since you can connect fine to another ISP, this may not be a
- burning issue to you any longer. The command list can be found on our ftp
- site in the Current Flashers directory.
