3.0 - 1B 4X and Control Characters
Sending the following command bytes to the CTOV box will cause the VPI output to assert the appropriate remote function line. The
VPI print/plot line will be placed low (raster mode) before the remote function line is asserted:
1B 41
remote clear
1B 42 remote line terminate
1B 43 remote end of transmission
1B 44 remote form feed
1B 45 remote reset
1B 50 ZZ asserts repeating remote line terminates from ZZ = 01 hex to
FF hex
NOTE:
These commands must be sent when the CtoV box is in print mode (section 2). The commands will be ignored and interpreted as
raster data if they are sent at any other time.
The CtoV box also obeys standard control characters that must be sent when the CtoV box is in print mode:
04
end of transmission
0A line feed
0C form feed
0D (carriage return - this byte is ignored)
