EM1500 Configuration
H
Disconnect from remote host (“hang up”). Note that on standard
modems, this controls the hook switch. There is no concept of a
hook switch on the EM1500, so this always disconnects the
current connection if one is established: H0 and H1 have the
same effect.
I
Modem identification. This returns the string “EM1500 0.0”
with the appropriate firmware version and release number
substituted for the “0.0”.
O
Return “on-line” from AT command mode. If there is a
connection or pending connection, this gets out of AT
command mode and back to normal data transfer mode.
Q0
Disable quiet mode (i.e., respond with numeric or English result
codes)
Q1
Enable quiet mode (no responses)
V0
Use numeric result codes
V1
Use English word result codes
Z
Reset modem settings to defaults (see
below)
