Modem Settings
Data compression needs to be disabled on external modems used
with RCM8. On U.S. Robotics Sportster® modems, the modem
command to disable data compression is AT&K0.
Error correction may or may not need to be disabled, depending
on your application and premise equipment. The modem
command AT&M4 allows the modem to select the error
correction mode; AT&M0 will manually disable error
correction.
Modem commands can be directly issued via the Modem Pass-
Thru mode in the RCM8 Modem Configuration menu. Refer to
Section 3.
