SPEEDSTER 288 INTERNAL FAX/MODEM
6.1 Before the Modems Connect
If your Speedster 288 does not respond to AT commands...
• Make sure you are in terminal mode. (Your communications software
should let you switch to terminal mode.)
• Make sure you selected the correct COM port and IRQ in your
communications software, or in your Windows Control Panel.
• Type in all upper (
AT
) or lower (
at
) case.
• There may be a COM port/IRQ conflict. (Refer to
Chapter 3
.) You will
need to remove your modem from the PC and change your COM port
and IRQ settings to COM port 3 and IRQ 5. If you change your COM port
and IRQ settings, also make the changes in your software and in Windows.
If your Speedster 288 does not answer the phone or does not “go off hook” to dial
a number...
• Make sure the phone cord is connected from the jack on the modem
labeled TELCO to an analog (standard) phone wall jack.
• Review your software manual to see what DTR operations are required.
• (
For answering
) Make sure your software has “auto answer” enabled.
If double characters are displayed on your screen (For example, AATT)...
Both your Speedster 288 and your communications software’s local echo
features are on. Turn one off by going into terminal mode (your
communications software should let you switch to terminal mode) and:
1. Typing
ATE0
(the last character is zero)
2. And then pressing the ENTER key.
