RM>How about a second question?  When you want to disconnect a

Ok...  Found my problem with the above.  You DO use the
ASYNC_SETMODEMCTRL function using the DTR_OFF value in the MODEMSTATUS
structure to lower DTR and DTR_ON flag to raise it.  My problem was I
wasn't allowing enuf time for the modem to detect the lowering of DTR.
By adding an event semaphore and blocking the calling thread till
carrier loss was detected, I solved this problem...unless someone has a
cleaner/easier way to show. :)
