- Hi

-
- S54=96 disables upper symbol rates
- these are parts of V34 negotiation, some older rockwell based modem have a V34 bug
- s54 =96 brings down the speck of the USR modem to be able to talk to these modems
- this is backed up by the fact that newer Rockwell based modems also can't talk to older rockwell modems
- although old rocwell can talk to old rockwell
