Subject: Custom asyn input EOS

Hi,

I have a motion controller I’m writing a driver for and it communicates by sending XML with no line terminators. This is proving to be a pain as any asyn reads time out. Luckily I know exactly what XML structure I expect back as the controller only uses this mechanism to respond to requests and it will always respond using the same structure the request was sent in. I would like to be able to set the input eos to the last element in the XML structure, eg, </sequencer_prog>. I tried to use the method asynOctetSyncIO->setInputEos() as this has an EOS string and length as parameters but looking at the implementation in asynInterposeEos.c I can see that the length of the EOS given is used in a switch statement and anything greater than 2 is invalid. Is there any way to specify a custom EOS of any length?

Thanks
Lee
