Connection with serial device (SPP)

Question

I try to connect with a bluetooth serial device (a robot, no standard device) which is working with every PC but not from my MAC. I can connect to the device (I use ZTerm) and send one character, but not more. If I send more, those characters are not send until I quit and restart ZTerm. Then (nearly) all characters are sent. I can get all characters sent by the device. It seems a problem of flushing the buffers at some level of the drivers. Any experience or idea?

Hi!, Ranothil: If you have the next cable and "null modem" (http://commerce.hpcalc.org/serialcable.php), you can transfer, anydata, from HP50G, to PC and viceversa, across Connectivity Kit (Conn4x), without problem. Please, see this link, with instruction's, for transfer data with serial cable, null modem and connectivity kit ... http://sense.net/~egan/skb/ and/or ... http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv017.cgi?read=125259 Note: Better, if you transfer data, from HP50G to, PC and viceversa, across the microUSB.
