CARROLL TOUCH Chapter 6 - Touch Application Program Interface (TAPI)
Touch System Programmer’s Guide 6-5
U = Uninstalls the driver.
Cn = Serial port. n may be 1 or 2. The default is 1. If the A and
I parameters are used, the C parameter is ignored.
Bn = Baud rate. n may be 3, 12, 24, 48, or 96. The default is
48.
Pn = Parity. n may be E (even), O (odd) or N (none). The
default is N.
Sn = TAPI software interrupt. n may be any unused software
interrupt. The default is 55H.
An = I/O address override. n may range from 0H to FFFFH.
The A and I parameters must be used together. An error
condition occurs if one override parameter is used
without the other being present.
In = Interrupt number override. n may be 2, 3, 4, 5, 6, or 7.
The A and I parameters must be used together. An error
condition occurs if one override parameter is used
without the other being present.
The command line is case insensitive and the command line parameters
may be arranged in any order. For example, to operate the RS-232
controller at a baud rate of 4800 with no parity through serial
communication port 1, you can type either:
RS232 C1 B48 PN
or
rs232 b48 c1 pn
If you wish to use the RS-232 driver with a serial port that uses a base
I/O address and/or interrupt number other than the standard values of
3F8H and 4 for COM1 or 2F8H and 3 for COM2, you may use the A
and I parameters to override the default values.
