After 12 hours of running the M34F the following can be observed:

ATI5 returns "NetComm Ltd." instead of a list of the data stored
in NVRAM. Is this a bug? It gives the list on the all of the USRs I've
tried . . .

I have a mail downfeed out on the Darling Downs.  He has some sort of
Rockwell based V.FC modem.  When he rings the Courier or the Sportster he
usually gets a 19,200 V.FC connect.  Files transfer at around 100%
(according to Bink 2.59).  This morning he connected at 28,800 V.FC,
however the transfers only managed 30-35% efficiency.

Regarding ATZ resetting the port speed. . .

ATI5 on the USRs lists the NVRAM settings.  These settings include the port
speed (there it is at the top left of the list).

AT&V (what sort of a command is that?) will list the NVRAM settings in
the M34F - there is no sign of any stored port setting to be reset by ATZ .
. .

Other than the above, I wouldn't think any of my callers would have spotted
the difference (so far)
