- You should really change this if you're using the modems to
- recieve calls. it won't affect performance in any way, but it will
- prevent people from dropping your modem into command mode (and being
- forced to drop the connection) any time they try to drop their own modems
- into command mode. Set S2=255.

- You may also want to set S13=1, this will tell the modem to reset
- on DTR drop, may prevent occasional modem lock ups.

- OUCH, I'm suprised the modem would even work connect at all with
- that firmware, from waht I had heard it was pretty horrible. The newest
- firmware (over a year newer then the one in use in those modems) should
- make a BIG improvement on ALL connections, not just those that are having
- problems.

- I certainly hope that they didn't promise that, 'cuz if they did
- they'd have been lieing. USR doesn't even come close to supportign the
- hundreds of ITU-T protocols (most of which are in no way modem related),
- they don't even support half of the ITU-T v.xx protocols (they are I think
- 54 different v.xx protocols), in fact, they don't even support ONE more
- ITU-T protocol than comparable modems, and they support fewer ITU-T
- protocols than many modems out there (eg all 4-wire LL modems). What
- these modems DO support, is both v.32terbo and vFC, neither or which are
- ITU-T protocols. The Courier is the only modem to support both these
- protocols. They also support HST.

- Actualy most Rockwells are fairly reliable with USRs (using
- current firmwares) and other Rockwells. Problems usualy arise when you
- try to connect a Rockwell to an AT&T chipset modem. For example, my
- Motorola Power connected to the Multitech BBS with a nice stable 28.8/28.8
- connection, while my Infotel (Rockwell Glue 'n Go jobbie) managed a
- whopping 19.2 connection, which didn't seem particularly stable, this is
- over the exact same phone line.
