It looks to me like "AT" does as much for me as "AT+FBU=0" does; it gets an
"OK" response.  What I'm concerned with is that HylaFAX may be behaving in
a particular fashion because it believes that HDLC frame tracing is
enabled... when it's not.  Does HylaFAX do anything differently when HDLC
frame tracing is enabled, or is HDLC frame tracing not handled at all by
HylaFAX other than issuing the Class2BUGCmd to the modem?

>Maybe we also should change Class2BUGCmd default to ""?

If HylaFAX is behaving in a fashion because it believes that HDLC frame
tracing is enabled, then I think that something ought to be changed so that
it knows the difference, but if HylaFAX doesn't do anything different when
HDLC frame tracing is enabled from when it is disabled, then I think that
config(5F) should read differently with regards to Class2BUGCmd.

Thanks

Lee.
