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 [<port #>] [BAUD
(300|1200|2400|4800|9600)] [DATA7]
[STOPS2] [PARITY (EVEN|ODD)]
[NOFLOW] [LF]
<port #> 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<string>|
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
<STX><string><ETX><LRC> 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 <seconds> is time to wait, defaults
to 30 seconds
CASE string is case sensitive
SPACE length of white space in target is
significant
MAX <integer> give up after that many
characters are received
QUIET <integer> give up if host silent that
many seconds
VAR <variable > target matched is returned in
<variable>
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 [<until-list>] (VAR <variable>
| FILE[APPEND] <fname>)
The <until-list> is replaced by one or more of:
MAX <integer> 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 <seconds> timeout in seconds, defaults
to 30
QUIET <seconds> give up if line quiet for
given number of seconds
PACKET terminated on receipt of packet,
returns 0 (may combine with END)
