Lee,

In answer to the last question: I don't know, I haven't had the chance 
to try sending to different destinations.

I don't think 'sendfax -B 4800' is going to work for us, as everyone is 
using Windows machines and I plan to have them send through WHFC. Asking 
them to run a SSH session and enter text on a command line just won't work.

So I'd like to try the other option, that is, get hylaFAX to avoid the 
higher speeds. Forgive my density, but I looked at 'man hylafax-config,' 
and I just don't understand what is meant by "force the Class1TMQueryCmd 
and Class1RMQueryCmd options." What is being "forced" here? The default 
setting of AT+FTM=? is what is listed in the modem documentation for 
querying the transmit speed, and explicitly giving this default value in 
the modem config file has no effect. On the other hand, if you replace 
the ? with a number (i.e., 48 which corresponds to 4800 bps), then this 
is the command for setting the transmit speed.

But if I do this, hylaFAX won't initialize the modem. var/log/messages 
shows an ERROR . The modem returns "OK" in response to the speed being 
set when hylaFAX appears to be expecting a comma-delimited list of 
possible speeds in response to its inquiry. Then it sits there in an 
infinite state of "Waiting for modem to come ready."

I am clearly missing something here.

Thanks

Michael Evans
