Some modems don't respond properly to ATH0 when the modem is already on
hook.  I'm attaching a patch which will remove ATH0 from the reset
sequence.  This may be the problem, but it could be due to a lack of a
pause after DTR ON, too (see below).

This is probably due to a lack of a pause after DTR ON.  I've seen this
problem surface in USR modems especially (but Elsas may also have the
problem).  Current CVS has this fix applied.  For the patch, see:
