.2 Tips for the Sender Modem

You have to make some adjustments for the modem that accesses your mailbox if you work with CoMa Voice.

Due to the answering machine announcement starting before data exchange, the preadjusted time for recognition of the carrier tone is not sufficient in most cases. The modem reports "No Carrier" after 30 to 60 seconds normally and disconnects. If you calculate the time for the start of the computer, the answering and the negotiation of the connection paramters you will find that at least 60 seconds are necessary. We recommend therefore to adjust the "Wait for Carrier Detect" to 90 seconds. This should eliminate all problems.

According to the standard Hayes command the register to change this time is at S7.

Please check in your handbook if the register S7 is fixed. Then you can set your register permanently to 90 seconds. The best solution is that you enter the terminal window of CoMa and send following commands:

ATS7=90

<Return>

AT&W 

<Return>

AT&V

<Return>

After entering the first two commands the modem will write "Ok" on your monitor. The total configuration has to be reported back by the modem after the last command. We are only interested that the value 90 appears in the register S7 "active profile".
