I don't stop and restart faxq regularly, should I?
here are loglines:

Apr 26 10:28:29 fax FaxSend[31299]: Error parsing "+FTM" query response: "OK"
Apr 26 10:28:29 fax FaxSend[31299]: /dev/ttyM14: Can not initialize modem.

Apr 26 10:28:33 fax FaxSend[31288]: /dev/ttyM14: Can not initialize modem.

Apr 26 10:27:35 fax FaxSend[31071]: Error parsing "+FRM" query response: "OK"
Apr 26 10:27:35 fax FaxSend[31071]: /dev/ttyM14: Can not initialize modem.

(oddly enough, pid 31071 log only these two lines...)

I see the default value is 30 seconds. I don't really understand how
should I tune it, maybe to allow a closer poll? Any hint here?
As I wrote in another post, I see that this kind of errors always
begin with a conversion problem of one or more pdf fax, but I don't
get how this is related to what I observe.
