Hanging Up
The H command is used to hang up the modem. After you have finished communicating with
another computer you must hang up your modem. Similarly, you must hang up the phone after
calling another person. If you don’t, no one will be able to call you and you may even be charged
for the length of time the phone was off the hook.
To hang up your modem:
• Type: ATH <E>
The modem will return an OK response message.
Stored Number Dialling
Your modem has the ability to store phone numbers which may be dialed at a later time. This is
similar to ‘abbreviated dialling’, which may be supported by your telephone.
To store a phone number use the &Z command. For example:
• Type: AT&Z1=012345 <E>
The phone number 012345 will be stored as phone number one. The S dial modifier is used to
dial a phone number that has been stored in your modem:
• Type: ATDS=1 <E>
The modem will dial stored phone number one.

Do not include an AT, D command, or S dial modifier in the stored phone number.
If synchronous mode 2 is being used, the ; (semi-colon) dial modifier should not
be included.
Answering Calls
As well as dialling other modems, your modem can answer calls made to it by other modems.
