Modify RSC Configuration Variables

Using the RSC GUI or RSC shell, set the following configuration variables as shown.

Table B-4 MultiTech Modem II RSC Settings

GUI Setting 

Configuration Variable Setting 

Serial Port Settings 

 

Baud Rate: 9600 

Enable hardware handshaking 

 

 

serial_baud 9600

serial_hw_handshake true

Alert Settings->Pager->Pager 1->Advanced 

 

Baud Rate: 9600 

Modem Init. String: &D3&E0&E14$BA1

 

 

page_baud1 9600

page_init1 &D3&E0&E14$BA1

Alert Settings->Pager->Pager 2->Advanced 

 

Baud Rate: 9600 

Modem Init. String: &D3&E0&E14$BA1

 

 

page_baud2 9600

page_init2 &D3&E0&E14$BA1

The string &D3 sets the modem to reset when DTR drops, the string &E0 disables error correction, the string &E14 disables data compression, and the string $BA1 turns off speed conversion.

To check that these settings are correct, use the rscadm show command.

Modify Modem Settings

Use the rscadm modem_setup command to enter the following AT commands:


# rscadm modem_setup
OK
ATZ (Reset modem)
OK
AT$BA1 (Turn off speed conversion)
OK
AT&W0 (Write out settings to modem)
OK
AT$SB9600 (Set serial port baud rate to 9600)
OK
AT&W0 (Write out settings to modem)
OK
AT$BA0 (Turn on speed conversion)
OK
AT&W0 (Store current settings to modem NVRAM)
OK

After executing these AT commands, you can verify the modem settings in NVRAM by using the ATL5 command:


OK
ATL5
B1 E1 M1 Q0 R0 V1 X0 &E0 &E4 &E6 &E8 &E10 &E13 &E14 %C0 #C1 *C0 &C1 
$MB9600 $SB9600 $BA0 &W0 
OK

After confirming settings, turn the modem off, reset RSC using the GUI or the resetrsc shell command, and then turn the modem on again.
