On the PC, support for the Centronix/Parallel Printer Interface and the Windows Print Manager has been added. The interface select code for LPT1 is 26, for the Print Manager it is 10. These can be changed if needed (see Chapter 10 of the User’s Guide, "Other I/O Destinations" and Chapters 5-9 in this manual).
The serial interface has been enhanced with XON/XOFF flow control. It is enabled by default. If you are porting existing programs that transfer binary data or ^S and ^Q characters as part of the data, you should turn off XON/XOFF flow control and turn on hardware handshaking with the statements:
CONTROL 9,100;0
CONTROL 9,5;0
CONTROL 9,12;0
The maximum line number in HTBasic has been increased from the HP limit of 32,766 up to 4,194,304. If you plan on also running a program on an HP computer, you should not use line numbers over 32,766.
