Question:
I'am trying to make an Internet connection using GPRS modem connected via serial. I configured modem bearer table to use multi-mode.tsy (mm.tsy) accordingly. However after starting connection, the etel server panics with a message "Program closed/ Program:EtelServer/ Reason code: MM.TSY/ Reason number:76. What's wrong?

Answer:
Etel server panic : 76 = "ETsyConfigAmbiguousModemTables"
This panic is raised because the MMTSY has two sets of configuration data for the modem bearer and is not able to decide which configuration to use.

To fix this problem you need to ensure that both the modem bearers in the commdb global settings table specify the same modem bearer. See ModemForDataAndFax and ModemForPhoneServiceAndSMS in the example commdb dump below.
