|I have had similar problems. A partial victory might be achieved by setting

this has the nasty side effect for non-hayes modems of possibly resetting
the D0 flag after the reset, which causes the next hangup to NOT reset the
modem.  for hayes modems you must remember to store the command into
non-volatile memory so that the reset will not turn off that option.
