Andreas .. first of all, let me thank you for your help/guidance. I'm
extremely impressed with your diligence and support in this news group. I'm
reporting back what I found in the hopes that someone else may benefit ..
As it turned out, the reason that lineOpen was failing on the second attempt
was because I had used LINECALLPRIVILEGE_OWNER |
LINECALLPRIVILEGE_MONITOR on the lineOpen command. When I changed this to
LINECALLPRIVILEGE_NONE, the second lineOpen succeeded. At that point, I
started seeing a failure on the second call to lineMakeCall
(LINEERR_RESOURCEUNAVAIL). A little digging found that the hComm handle
was not being closed properly on the disconnect, making it unavailable for
use on subsequent calls. At this point I can connect/disconnect repeatedly
without any problems.
Thanks again.
Jerry
