One of the disadvantages of an internal modem is that you can't see (by your front panel lights) that your modem has kept your phone connection even though your computer/terminal-emulator has signed off. The power on/off (cold boot) turned off your modem as well & lost the connection, the warm-boot did not. For hayes compatible modems & other communications programs (I don't have/know crosstalk) hanging up (crosstalk bye???) should work, to hang up "manually" within your emulation program - if you have a hayes compatible modem - enter "+++" wait a sec (it helps if you have reply mode set on) then enter "ATh0" - thats a zero at the end not an oh. Good luck. Andy Dicker. -------

Good luck. Andy Dicker. to hang up and resurrect the phone "manually" within *DOS*, you can issue the commands from within a batch file (a sample "HANGUP.BAT"): ECHO OFF ECHO HANGING UP MODEM ECHO ATH > COM1: /* OR COM2: ECHO DONE! for more on batch file madness with your modem, see PC MAGAZINE 8:5:233-238. -- .^. michael regoli /|\ ...ihnp4!inuxc!isrnix!mr '|!|` <mr@isrnix.UUCP>
