CIGAL Reference Manual, Chapter 3 (Functions): comread

Comread -- Read from serial communication port

usage: vdst = comread(chan,nchars,flag)

Read byte data from a serial input port. CHAN must be 1 or 2. NCHARS is the maximum number of bytes to read; if NCHARS is 0, all the bytes currently in the buffer are read. FLAG can be used to specify reading options (its default value is 0).

         FLAG options:
                        1 - wait until NCHARS characters have been read otherwise reads current
                        available data up to NCHARS bytes
                        2 - return current byte count only (don't read data)

NOTE: The serial input port must be configured before it is read. To configure the port you load the configuration bit-flag into the COM1 (or COM2) number variable (see COM1(4)).
