The initialization strings invoked by Remote Access Server are located between the “Initializing modem” and “Waiting for a call” lines in the modem log file. Typically, there are three or four AT command sequences listed. The last command sequence is usually constructed using the options you have selected in the Modem Properties dialog box. This string usually contains entries for compression, error control, timeout settings, and so on. The strings proceeding the options init string are common to all configurations of this modem and contain reset, mode, and response code configuration. AT commands which are particularly important to proper modem sharing operation are those which specify the response format of the modem. These strings define how the modem reports negotiated speed, error control, and compression information upon establishing a carrier and whether this information is to be reported in numeric (V0) or verbose (V1) mode. Using your modem’s AT command reference, determine which commands strings differ from the modems default settings and construct new initialization strings for IRC using these settings. If you are unsure of which settings may be important, try using the strings verbatim. In this example, the IRC primary initialization string could be set to “AT &F E0 %U2 V0 &D2 &C1 S0=0” and secondary initialization string to “ATS7=60\T0L1M1\N3%C3\Q3B0X4.”
