I do NOT want to do RS232 using PIC code - I want speed...!!! yea there is. Its the 17c42. Its pretty expensive though. As far as speed I have done 19.2Kbps. How fast do you need it to be? If it really bothers you about "waisting" time use something like the 84 or the 71 which have interupt. preload the RTCC and service and interupt. yes it it a waist, kind of. But that depends on you needing the RTCC or not. Also the 17c42 is large(40 pin). Most of my work is B-size cards for VXI and a 40 pin device had better be well worth the price. later John ----------------------------------------------------------------------------- John Johnson Team OS/2 member | johnsonj@bga.com | johnsonj@utdallas.edu ----------------------------------------------------------------------------- And the Seventh version of OS/2 raised into the air its bow of blue steel and cried," It.
