This test verifies the integrity of the local modem’s transmit and receive
circuits.
1. Set the DTE speed.
2. Make sure the modem is in terminal mode (no connection made).
3. Issue an AT&Q0 command to the modem. This sets the modem to the
direct mode.
4. Set timer register (S18) for desired test time (in seconds). Example:
“ATS18=10” provides for a 10 second test.
5. To begin, type AT&T8 [ENTER]. The modem responds with OK.
6. After the number of seconds specified in S18, the modem should
respond with 000 (meaning 0 errors were found during the self test).
