Interfacing SB700EX and SBL2EX

[abbu2390]

hii,

i need some help ...

im sending a command from SB700EX to SBl2Ex but sbl2ex is not recognizing it.But when i send same command from mttty (serial port) it is responding to the command.Even checked output from sb700ex using mttty it is sending same command as that from mttty.

Both have same baudrate and 8N1- 8 data bits,none parity ,one stop bit and pin connection also good.

i don't know what going wrong..

Exact same cabling/wiring? I would verify rx and tx are in the null modem configuration.
