Screen(’Command not recognised’+newl,Fromctrl);
It can be seen that programming the serial ports that
NewCOM provides is simple in Turbo Pascal, although the
details of Pasterm may obscure this. The standard Pascal
functions of Assign, Reset, ReWrite, Read, Write and Close
allow the user to access the serial port. The port parameters such
as Baud rate and parity can be set with the Intr procedure, which
gives access to the BIOS asynchronous services.
