- NAME
-
- comsend - send file(s) over the serial communications line
-
- SYNOPSIS
-
- comsend [-options] file1 file2 ...
-
- DESCRIPTION
-
- COMSEND is a program that will send files over a communications line
- connected to one of the serial ports (COM1: or COM2:) of the PC.
-
- COMSEND will automatically set up the speed, parity, number of data
- bits and stop bits for the serial port before sending the file(s).
- It can also use flow control.
-
- In addition, COMSEND can go through a sequence of operations
- needed to establish the connection. This sequence is specified by a
- string of characters called the CONNECT SEQUENCE.
-
- After the connnection is established and the file(s) transmitted,
- COMSEND can go through another sequence of operations to disconnect.
- This sequence is specified by the DISCONNECT SEQUENCE.
-
- If no filename is specified, the standard input is used. Wildcard
- characters are allowed in filenames.
-
- CONFIGURATION
-
- COMSEND needs to be configured to set up the default parameters
- (speed, parity, connect/disconnect sequences etc.). In order to
- configure COMSEND, `cd' to the directory that contains COMSEND.EXE
- and enter
-
- comsend -C
-
- For each parameter, the choices are displayed along with the
- current value. To keep the current value, press the return key.
- To change it, enter a value from the choices displayed.
-
- Configuration cannot be done if COMSEND.EXE file is not in the
- current directory or is READ-ONLY.
-
- COMMAND LINE OPTIONS
-
- Any of the configured values may be overridden during execution
- of the program by entering a command line option. For example,
- entering "comsend -b1200 somefile" will use 1200 baud even though
- COMSEND may be configured for 9600 baud.
-
- Available command line options are:
-
- -bxxxx use baud rate xxxx. xxxx = 110, 150, 300
- 600, 1200, 2400, 4800 or 9600
-
- -px use parity x. x = N, O or E
- N=none, O=Odd parity, E=Even parity
-
- -nx use x as number of data bits. x = 7 or 8
-
- -sx use x as number of stop bits. x = 1 or 2
-
- -mx use serial port COMx:. x = 1 or 2
-
- -fx use x as flow control. x=D for DTR/CTS, X for XON/XOFF,
- N for No flow control
-
- -cx..x use connect sequence x..x. Sequence x..x should not contain
- any spaces - use \s for a space
- (see section on connect/disconnect sequences)
-
- -dx..x use disconnect sequence x..x. Sequence x..x should not contain
- any spaces - use \s for a space
- (see section on connect/disconnect sequences)
-
- -v verbose mode: displays incoming characters and additional
- information (see NOTES section)
-
- -C Configure COMSEND (see CONFIGURATION section)
-
- CONNECT/DISCONNECT SEQUENCES
-
- These are two sequences of commands that are to be executed
- in order to establish connection and break the connection.
- These sequences are specified during configuration
- and may be overridden by the -c and -d command line options.
-
- The list of commands available is shown below:
-
-
- t Toggle DTR (set low (0), delay, set high (1)).
- Delay duration 500 ms unless set by command T (below).
-
- Tnnn Set DTR toggle time period to nnn X 0.1 seconds.
- 'nnn' MUST be a 3 digit number - 000 to 999
- (0 to 99.9 seconds).
-
- b Send break.
- Duration 200 ms unless set by command B (below).
-
- Bnnn Set break time period to nnn X 0.1 seconds.
- 'nnn' MUST be a 3 digit number - 000 to 999
- (0 to 99.9 seconds).
-
- p Pause for 0.5 seconds.
-
- P Pause for 2 seconds.
-
- Dnnn Pause (delay) for nnn X 0.1 seconds.
- 'nnn' MUST be a 3 digit number - 000 to 999
- (0 to 99.9 seconds)
-
- r Transmit a carriage return over the COM port.
-
- n Transmit a line feed (newline) over the COM port.
-
- R Transmit a carriage return followed by a line feed
- over the COM port.
-
- "xx..xx" Transmit the string in quotes over the COM port.
- The string may contain special characters (\r,\n,
- \" etc. - listed in the next section).
-
- d"xx..xx" Display the string in quotes on screen.
- The string may contain special characters.
-
- m"xx..xx" Try to match the characters received over the
- communications line with the string in quotes.
- If the match FAILS, COMSEND issues an error
- message and ends.
- The string may contain special characters.
- The time period over which COMSEND will wait to find
- a match may be set by command M (below).
-
- After a command m, it is a good idea to use a command
- p, P or dnnn followed by a command f to make sure
- that all characters received after the match will
- be read and flushed before the next operation.
-
- Mnnn Set timeout for the m command to nnn seconds.
- 'nnn' MUST be a 3 digit number - 000 to 999
- (0 to 999 seconds). The default is 20 seconds.
-
- q"xx..xx""yy..yy"
- Try to match the characters received over the
- communications line with the first quoted string.
- If the match SUCCEEDS, COMSEND displays the second
- string and ends.
- Both strings may contain special characters.
- The time period over which COMSEND will wait to find
- a match may be set by command Q (below).
- If the second string is to be empty, use "".
-
- After a command q , it is a good idea to use a command
- p, P or dnnn followed by command f to make sure
- that all characters received after the match will
- be read and flushed before the next operation.
-
- Qnnn Set timeout for command q to nnn seconds.
- 'nnn' MUST be a 3 digit number - 000 to 999
- (0 to 999 seconds). The default is 5 seconds.
-
- e Turn echo mode on. Displays incoming characters
- as they are read by one of the other commands.
-
- E Turn echo mode off (see command e).
-
- f Flush receive buffer. It is a good idea to use one of
- the delay commands (p,P,dnnn) before this.
- If verbose mode is turned on from the command line,
- characters will be displayed as they are flushed.
-
- EXAMPLE: For example, the connect sequence PRp"dial"m"no""123\r"
- will cause the following to occur before file transmission:
-
- 1) Pause for 2 seconds.
- 2) Transmit a carriage return followed by a linefeed.
- 3) Pause for 0.2 seconds.
- 4) Transmit the string "dial"
- 5) Wait till the string "no" is received.
- 6) Transmit the string "123" followed by a carriage return.
-
- SPECIAL CHARACTERS ALLOWED IN STRINGS
-
- The following special characters are allowed in strings (i.e. within
- double quotes) :
-
- \r carriage return (without an added linefeed)
- \n line feed (newline)
- \f formfeed
- \s space
- \e escape
- \b backspace
- \\ the character `\'
- \" the character `"'
- \nnn the character with ascii code nnn (3 digits, DECIMAL)
-
- For example, the string "\fmyname\r\n\f" consists of a
- formfeed followed by `myname' followed by a <CR>, a <LF> and a
- formfeed.
-
- NOTES ON WRITING CONNECT/DISCONNECT SEQUENCES
-
- Use of a command p, P or dnnn followed by a command f is recommended
- before sending a reply to the device being communicated with.
- This ensures that all characters that were sent by the device are
- read before the device is replied to.
-
- The results obtained when using the verbose or echo mode may be
- different from when not using it: this is because in these modes,
- the program runs slower and the receive buffer is not emptied out
- as fast.
-
- While transmitting the file(s), all characters that are received
- accumulate in the receive buffer. These may be displayed by
- placing appropriate commands in the disconnect sequence.
-
- Flow control is used only for transmission.
-
- If a connect fails, COMSEND will still try to disconnect using
- the disconnect sequence.
-
- All screen output maybe redirected into a file.
-
