ATH1, DT1234567
“H1” takes the telephone off-hook, “,” causes the Z02215 to wait the time in S-Register S8 (default 2 sec-
onds), and “DT1234567” causes the Z02215 to tone dial the number 1234567. Use S-Register S8 to
increase or decrease the delay before dialing.
Similarly, to answer the telephone, use
ATH1,A
Alternatively, design a pick-up detection circuit that does not respond for a sufficient period of time after
the Z02215 has taken the telephone off-hook.
Problem #5 - Unformatted Caller ID
Versions: Z02215 ROM Codes 4508 & 50A5
Updated: October 03, 2001
Problem: When unformatted caller ID option is used (AT#CID=0), the final octet of the caller ID packet
(the checksum octet) is not sent to the host.
Solution: No solution is possible. All data octets are passed onto the host as received but without the
checksum octet it is not possible to ensure the accuracy of the data packet. Use the formatted option if pos-
sible.
