RS-232 control cambride audio amplifier

I try to control my Cambridge audio amplifier over RS-232. Till now I have no succes.
For example the following command will turn the amplifier in standby

#1,01,0\r
I set the baudarate, parity, databit and stopbit according to the manual
When I use the following command:
hs.SendToComPort 1,"#1,01,0\r"+vbcr

Nothing happens. The comport is working because I can control other equipment.
Has someone experience with the integration of camebridge equipment in HomeSeer?

The \r is a return and the vbcr is also a return. I don't know if this can be an issue. You could use a serial monitor application to see what is send and returned.

Problem solved. There were multiple issues. I used a female to female cable according to the supplier. After using a null modem cable I was able to receive the RS-232 data. Than it appears that additional "0"'s were required (compared with the manual).
