I tested on a NetBSD/amd64 6.1.4_PATCH system, with the same symptoms
on com0.
Using an usb-serial adapter as ucom0, sending a single fax worked, but
when having two faxes in the queue, the dialing for the second one
happened while the modem was resetting and thus ignored. I suspect that
in this case sending the single fax worked because the usb stack
caches enough of the data...
In both cases, being next to the modem with the laptop, it looked
to me like flow control didn't work.
Anyway, an arm-specific issue can be ruled out - there's a com
driver or tty driver regression in netbsd-6.1 (compared to netbsd-5).
