Chapter 13 - Diagnostics & Troubleshooting
13-7
You can make a data connection with a remote modem, but encounter frequent
errors during data transfers.
Solutions
1. Your modem and communications software may be configured for different
flow control methods. Be sure your modem and software are both using
hardware (RTS/CTS) flow control or software (XON/XOFF) flow control.
2. To verify that your modem and communications software are using the same
flow control method, type AT&T8 and press the Enter key with your modem
in the command state. You should see a smooth “stair-stepping” ASCII test
pattern flowing diagonally across your screen.
Connect Problems
Problem
Your modem disconnects while communicating with a remote system.
Solutions
1. The remote system may have hung up. Type ATI2 and press Enter to view the
link status report, which will include the reason for the disconnect. For
information on understanding this report, refer to your ZyXEL Modem
Reference Manual.
2. You may have subscribed to Call Waiting and received an incoming call that
interrupted your data connection. See your telephone directory for
information on disabling Call Waiting.
