BOCA PRO16 Reference Guide
Although most telephone exchanges support tone dialing, there are still
a few pulse only exchanges. If you can hear a continuous dial tone when
you lift the handset, you will probably be able to tone dial. If you are in
any doubt, use pulse dialing. The modem will automatically pulse dial
if you have not previously included either the T or P modifiers in your
phone numbers. Exchanges that support tone dialing generally support
pulse dialing as well.
More information about dial modifiers can be found in the Command
Descriptions section of this guide.
Hanging Up
To hang up your modem when operating in V.25bis mode, lower DTR.
Your modem will hang up whenever DTR goes low.
Stored Number Dialing
Your modem has the ability to store phone numbers for redialing at a
later time.
For example, to store a phone number use the PRN command:
• Type: PRN 1;012345 <E>
The phone number “012345” will be stored as phone number one.
To dial a phone number that has been stored in your modem:
• Type: CRS 1 <E>
The modem will dial stored phone number one.
Stored phone numbers are shared by V.25bis mode and AT Command
mode. Thus, if you store a phone number while AT Command mode is
active, you may dial that store phone number in V.25bis mode, or vice
versa.
Direct Dialing
Direct dialing refers to your modem’s ability to dial a stored phone
number when the DTR signal of your computer is raised. This form of
dialing is particularly suited to synchronous computers and is referred
in other parts of this guide as ‘DTR Dialing’.
FThe &M command (used to select various methods of DTR dialing in
AT command mode) has no effect when the mode is operating in
V.25bis command mode.
