[efax-users] flow control did not work

["James L. Morton" <jmorton@xxxxxxxxx>]

Hey,
	I recently installed a new fax server.  I've been using the old
one for about 2 years with not too many problems.  The new server is
pretty much the same w/ eFax 0.9 (Stable) and the same 4-port fax modem
(V2.200-V90_2M_DLS ROCKWELL AC/K56).

	The old server works fine, but the new one errors out w/ "flow
control did not work".  If I use hardware flow control (-oh), I get the
same error.  If I use virtual flow control (-of) some fax machines work
fine, but others error out with "DTE to DCE data underflow".  Any ideas
what the problem could be?  I've attached logs below:
