Caution - Caution -

Do not insert or remove a PCMCIA card while your system is suspending or resuming. The PCMCIA card will not be recognized after the resume operation.

If an application is accessing a PCMCIA serial/modem card while the system is being suspended, a HANGUP condition may occur which may cause the application to terminate.

For example, if you used the tip command to access a PCMCIA serial/modem card while trying to suspend your system, the tip command automatically exits when your system resumes. Other applications, such as UUCP or PPP, may try to automatically access the PCMCIA serial or modem card.
