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.
