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 $BA1 turns off speed conversion.
To check that these settings are correct, use the rscadm show command.
Use the rscadm modem_setup command to enter the following AT commands:
# rscadm modem_setup OK ATZ (Reset modem) OK AT$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.
