SM Appendix
Solution
In the User Tools, check the dial-up user and dial-up
password settings
Check the setting of SP5816 160 to determine
whether the setting for the AT command is correct. If
this SP setting is correct, then the problem is a bug in
the software.
The problem is on the external power supply line, so
there is no corrective action on the machine.
Use SP5985 1 and set the NIC to "0" (Disable) to
disable the network board.
Replace the modem board.
