Serial Printing Utility Program
SERPRN.EXE is a DOS utility program that allows you to set
up an Allegro serial communication port to send output to a
printer. If a program is designed to use a parallel printer port,
SERPRN redirects the parallel port settings to a serial port. It also
sets the communication parameters and software and hardware
handshaking.
This program can be used in place of the Mode command. Like the
Mode command, you can call SERPRN from the AUTOEXEC.BAT
fi le so printing is automatically set up.
The parameters you can specify when executing this program are
listed below.
COM1 COM port to be used (COM1 or COM2)
9600
Baud rate (1200, 2400, 4800, 9600, 19200, 38400, 56800,
115200)
n Parity (n - none, e - even, o - odd, m - mark, s - space)
8 Number of data bits (7 or 8)
1 Number of stops bits (1 or 2)
x Enables XON/XOFF handshaking
c Enables CTS hardware handshaking
d Enables DSR hardware handshaking
q Enables quiet mode
z Disables the redirection of the COM port
? Displays help
t Sets time out (number between 1 - 15)
To execute this program, type the command followed by your
parameter choices. The syntax and the default settings (no
handshaking) are shown below:
Serprn com1 9600 n 8 1 x
A space must separate each parameter. The fi rst parameter is always
the COM port followed by the communication parameters (these can
be entered in any order). The hardware and software handshaking
can be used separately or together. Normally, only one handshaking
method is used at a time.
Generally, an output list is shown after SERPRN is invoked
informing you how the utility has set the communication port. You
can disable the output listing with the quiet mode parameter (q).
