Can I safely use a zero? Just so that >the modem knows it is still connected...thanks a meg. What character you can safely send depends entirely on what the other end is looking for. If a is innocuous, it will do fine. If a zero is innocuous, it will do too. One possibility is to send a character followed by a backspace, if appropriate on the other end, and if it does what you expect. -larry -- The only things to survive a nuclear war will be cockroaches and IBM PCs. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
