TRAKIAN
program
Command
line options
A version
compiled for every COM port can be downloaded. These executables are compiled
for a COMn, a baudrate of 19200 baud, NO parity, 8 bits of word length
and 1 stop bit.
This is commonly refered as "8N1, 19200bauds" for BBS or other communication
systems. When launching
the program from DOS or in DOS mode for win.... parameters can be
entered on the command line. Each parameter
consist of a string followed by the equal sign without any space
between the string and the '=' and after the value of the parameter.
Thus, to select the COM2 port, the line look like this:
">TrakianLC COM=2" and adding the baudrate selection: ">TrakianLC COM=2
BAUD=38400" The commands
possible are: The COM
port the program shall use as Input/Output. It can range from 1 to
3 Thus: COM=1 COM=2 COM=3 COM=4 The baudrate:
from 600 bauds to 115200. Thus from BAUD=600 to BAUD=115200 To note
that the baudrate is depending from the hardware you have. Thus,
the
program CAN use these speeds but maybe your system can NOT.
Recent systems use chips of the 16550 family this kind of components
being equiped with a "FIFO" of 16 characters. Older system use 8250
components not having a FIFO. They can not use fast baudrates! But
this
depend also from the CPU you have. Running on a Pentium without FIFO
can permit to reach very fast speeds while a 386DX33 can not follow
the baudrate.
BUT many recent systems equiped with Pentiums use 8250 chips
too. Many times differents chips are used on different ports. Dont worry:
the system shall detect which kind of component is used and decide of
the best choice for each COM. The parity.
Normally 'NO' is used for most communication programs. The parity can
be O (odd) E(even) M(mark) S(space) N(no) Thus: PARITY=N for example.
The word
length: 7 bits or 8 bits. So BITS=8 The stop
bits: 1 or 2. So: STOP=1 or STOP=2 Many parameters
can be entered on the command line every being separated of the following
by a space or a separator accepted by DOS. No quote are necessary. But
no quote are allowed around
the value of the parameter. This is to say that BAUD=9600 is valid.
But BAUD="9600" is NOT! And
BAUD= 9600 is also not valid. Like BAUD =9600 is not valid. To
note that many parameters can be changed from the ZMODEM window selecting
the <F10> key and than selecting a menu.
But this not permit to change the COM port the program has selected
when launching.
Thus, if you have not the right selection, at least the: >TrakianLC
COM=..... must be used to select a particular COM port. It
is to notice that these commands can be entered in a batch file.
You can create a batch file named "Trakian.bat" with inside the above
selected commands required. A future
revision shall have more parameters like a "batch file", an "Ini file",
selection of the root directory, .... and others. Some comment
on the selections:
The parity is NOT NECESSARY. The communication programs used not
need it and have controls included in the stream.
8 bits is required. Because the ZMODEM protocol used require this
word length. But you can use the program to communicate with other
programs
and make some tests.
And as generality, using different parameters than 8N1 shall slowdown
the transmission rate!
So: YOU CAN .... but you probably need only to change the baudrate,
at most the COM port used!
