Problems using a modem
My modem is not working correctly in Windows 95.
Try disabling the “Use flow control” or “Use error control” options for the
modem. To do so, follow these steps:
1. In Windows 95, click the Start button, choose the Settings menu item, and
then choose Control Panel.
2. Double-click the Modem icon.
3. Click the Properties button.
4. Click the Connection tab in the dialog box that appears.
5. Click the Advanced button.
6. Deselect the “Use flow control” or “Use error control” options, and
click OK.
If you are having trouble connecting at higher baud rates, try setting the
modem speed to 19,200 baud or less.
When I try to use my Mac OS communications software, I get an error that says the
selected port is in use.
Your Mac OS communications software may be trying to use a port that is
assigned to the PC Compatibility Card. Open the PC Setup control panel and
unassign the selected port by setting it to None.
After I assigned a PC COM port to a Macintosh serial port, my computer did not
start up properly.
This problem can occur if you are using Apple Remote Access (ARA) 2.0
or 2.0.1. To correct the problem, restart while holding down the Shift key to
temporarily turn off all system extensions. Then remove the Serial Port
Arbitrator from the Extensions folder inside your System Folder, and restart
your computer. (Before you use ARA, unassign the PC COM port and restart
the Mac OS environment.) You can also correct this problem by upgrading to
ARA 2.1.
