I have a Bocca 33.6 hardware ISA modem that refuses to quit ! It works fine , but even though the computer has closed the connection , the phone line remains busy , this also occurs even when the computer is shut down !! I also have a Lucent Technologies 1641 modem w/ the same problem (different computer)...I realise I should just replace these , but if there is a fix I want to give it a try just for the learning experience.
Thanks
Bob
