ZyXEL U-336 E modem - serial communication question

[Blokk]

Hello People!

I have to deal with an old modem which has serial port comm too.

I wonder what would be the best approach to make a serial com API for this instrument. First I had even a problem with a default activated echo mode, but I managed to turn it off. Moreover, the unit responds with termination characters BEFORE and AFTER the response bytes, see my snippet below. I can easily program around this, turning off the term char, then capturing the timeout error, and finally parsing out the response part between the "/r/n" parts. Are you aware of something better to do?

Thanks, and I attached its manual too!
