PORT (155) allows the site to manipulate a serial
port to communicate with devices connected to that
port.
Options: Open, Send, Wait, Receive, Flush,
Close
Open option initializes the port:
PORT OPEN [] [BAUD
(300|1200|2400|4800|9600)] [DATA7]
[STOPS2] [PARITY (EVEN|ODD)]
[NOFLOW] [LF]
SC port number, defaults to 2
BAUD baud rate, defaults to 2400
DATA7 7 data bits, defaults to 8
STOPS2 2 stop bits, defaults to 1
PARITY parity, defaults to none
NOFLOW turns off flow-control
(normally XON/XOFF)
LF adds CR LF to lines (default is CR)
Send option transmits characters from string or
file, or causes a break:
PORT (SEND[LINE] <string>|
SENDPACKET|
SENDSLOW<string>|
SENDBREAK|SENDFILE <fname >)
SEND <string> <string> is sent to port
SENDLINE <string> <string> is sent
followed by a CR (and LF if LF option
was used in OPEN)
SENDBREAK causes a break on the line
SENDFILE <fname> sends file as lines
followed by CR (and LF if LF option
was used in OPEN)
SENDPACKET <string> sends
<string> where LRC is
the XOR of <string> and ETX
SENDSLOW <string> string is sent one char. at
a time paced about 1/4 second apart.
Note: This command may be used to
cause a modem to dial, etc., by sending
the appropriate modem command. Often
a break may be used to cause the modem
to hang up the phone.
Wait option pauses until a string matching the
specified string (or any of a list of strings) is
received or until timeout is reached:
PORT WAIT <option-list> FOR <string>
[<string>...]
The <option-list> is replaced by one or more of:
TIME is time to wait, defaults
to 30 seconds
CASE string is case sensitive
SPACE length of white space in target is
significant
MAX give up after that many
characters are received
QUIET give up if host silent that
many seconds
VAR target matched is returned in
ECHO display characters as received
The keyword FOR signals the end of the option
list and the beginning of the string list. Each
string may contain control codes (for example,
~0D or ^M) or wildcard characters (@s).
If any string contains internal spaces, it must be
enclosed in quotes (‘‘this string’’).
The return code is the number of the string that
was matched (for example, 1 if the first (or only)
string was matched).
Receive option captures incoming characters in
variable and/or file:
PORT RECEIVE [] (VAR
| FILE[APPEND] <fname>)
The <until-list> is replaced by one or more of:
MAX get the given number of
characters (defaults to 39 if VAR, 80 if
FILE)
END <string> until any character in the
string is encountered (this option may
appear multiple times), defaults to LF
and FF
TIME timeout in seconds, defaults
to 30
QUIET give up if line quiet for
given number of seconds
PACKET terminated on receipt of packet,
returns 0 (may combine with END)
