Hello friends, I am trying to communicate with a programmer memory from Unix (HP-UX) via serial port.
Well, I have some code ready stty parameters to achieve communicating the device with the computer, but I have my doubts. I would like to know if you have some code fragment where you use the stty command, something generic for a connection to the serial port.
We're running SCO Unix Openserver 5.05 and I'm having trouble with serial communication between the com2 serial port and a handheld device. Downloading data from Unix to the handheld works perfectly, but the other way around creates a major problem. I don't know whether it's a buffer overflow or... (1 Reply)

Hi again,
I spoke with Keyspan and they assured me the USB to Serial device was working if I could use the Screen tool.
I asked why I was unable to redirect stdin/stdout to and from the /dev/tty. device and was told there was no reason I shouldn't be able to do so.
I have tried:

Hello!
I am working on an application which reads environmental instruments which have serial ports. The application requires a serial port to be present to talk to the device (i.e. /dev/ttyS0 ). In some instances the environmental devices will be 100's of yards away from the computer, so a... (5 Replies)
edit: never mind; mods please delete. I finally got so frustrated I figured it couldn't be the code and it must be the device on the other end. After pulling it out of its cradle, I realized it was a different model number than the one I was using before, and wasn't accepting my... (1 Reply)

STATSERIAL(1) User Commands STATSERIAL(1)NAME
statserial - display serial port modem status lines
SYNOPSIS
statserial [-n | -d | -x] <device-name>
DESCRIPTION
Statserial displays a table of the signals on a standard 9-pin or 25-pin serial port, and indicates the status of the handshaking lines. It
can be useful for debugging problems with serial ports or modems.
The optional device-name parameter is the full name of the device file for the serial port in question. If not specified, the default is
taken from the environment variable MODEM if set, otherwise /dev/cua1.
COMMAND-LINE OPTIONS
Each of the command line options is mutually exclusive.
-n Normally statserial will loop continuously, updating the status at one second intervals; you can exit using Control-C. The -n option
disables looping.
-d
With this option the status of the modem is printed as a decimal number. The bits are encoded as follows (XXX indicates unused bits):
+---+---+---+---+---+---+---+---+---+
| 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
+---+---+---+---+---+---+---+---+---+
|DSR|RI |DCD|CTS|XXX|XXX|RTS|DTR|XXX|
+---+---+---+---+---+---+---+---+---+
-x This option is the same as -d, except that the output is in hexadecimal.
BUGS /LIMITATIONS
Statserial only works with devices that support the TIOCMGET ioctl.
You need permission to read the device file.
The device file may be locked if other applications are using it.
