V.25BIS - CRN Dial
This command allows you to dial a telephone number. The basic dialling command is:
CRN followed by the telephone number.
For example:
To dial the number (09) 111-1234
•
Type: CRN091111234 <E>
You can use hyphens, spaces or parentheses. They will be ignored by the modem, but they will
make it easier to read the command line.
For example:
CRN (09) 111-1234
