3. Send film parameters (Code #2)
Instructs the monitor to send the parameters for film # n to the host computer. A
description of the film parameter list is in
Table 10-5 .
Format: Header, Address, Instruction=2, Length=1, Film#(1-100), Checksum.
Example: To instruct the monitor to send the parameter list for material #15 the
computer would send:
Chr$(255)+Chr$(254)+Chr$(1)+Chr$(2)+Chr$(1)+Chr$(15)+Chr$(237)
4. Receive film parameters (Code #3)
Instructs the monitor to enter all the incoming film parameters for film # n into
memory. The parameters must be in the same order and format as the above film
parameter list.
Format: Header, Address, Instruction=3, Length=13, 1 byte, Film# (1-100), 12
