Symptom Charts/Global Village Modem “Busy Serial Port” - 20

 

Resetting modem in 

TelePort Control 

Panel gives message: 

“The current port is 

busy and cannot be 

opened. Quit any open 

communication 

application, or turn 

off AppleTalk in the 

Chooser (if the 

modem is connected to 

the Printer port), 

and then reopen the 

TelePort control 

panel.”

Here’s an alternative fix that doesn’t require GlobalFax 2.5.2P 

Update:

1 Replace corrupted control panel in System Folder with 

uncorrupted copy of TelePort Control Panel found in Control 

Panels folder on backup CDs.

2 Set AppleTalk to “Active” and select LocalTalk as the 

AppleTalk Connection in Network Control Panel.
