We have an old Ericsson GM12 with a custom-made serial cable that does
not have the control signals wired. When running Kannel 1.2.0, no
communications occurs. Turning off hardware flow control helps.
Attached is a patch against Kannel 1.2.0 that add an extra directive to
the modems group (disable-crtscts). Might help some people.
Regards,
Eric Yeo
