No one replied to my earlier plea, but I refuse to beleive that everyone was
stumped by this one, so I'll ask again:

I nead to read data from the serial buffer on the HP48SX whenever a line-
feed or carriage return is received into the buffer from the 4-wire port.
I would like to know if there is a way of checking the buffer to see if it
received a lf/cr before I do an SRECV.  Is there any way of checking this!?

I have tried just SRECV'ing in how ever many char's BUFFLE returns, but I
seem to loose some of the data when I do it this way.  I feel that if I could
force my program to read **ONLY** after a cr/lf, I would no longer loose data.

If anyone has any suggestions PLEASE RESPOND.  If I am not expressing myself
clearly enough, let me know and I will try to be more explicit.  If I could
figure it out myself, I would!  I'm just asking for suggestions, so please
help!  Thanks alot in advance (since I know THIS time SOMEONE will answer :-).

Later...                                    Leif Johnson
