serial port configuration
I am having trouble with a device connected through a serial port on my sun workstation ( I am running solaris 7).
The seriel device works on an identical workstation running the same o/s version but when I move it to the initial workstation it doesn't work. I am using an rs232 serial cable and am wondering what could be causing the problem. Is it possible that the transmit revieve and ground pins are configurable on the seriel port through the o/s and that they have been altered somehow. If so is there a way to reset them.
Any thoughts ?

LEARN ABOUT SUNOS
console
console(7D) Devices console(7D)
NAME
console - STREAMS-based console interface
SYNOPSIS
/dev/console
DESCRIPTION
The file /dev/console refers to the system console device. /dev/console should be used for interactive purposes only. Use of /dev/console
for logging purposes is discouraged; syslog(3C) or msglog(7D) should be used instead.
The identity of this device depends on the EEPROM or NVRAM settings in effect at the most recent system reboot; by default, it is the
``workstation console'' device consisting of the workstation keyboard and frame buffer acting in concert to emulate an ASCII terminal (see
wscons(7D)).
Regardless of the system configuration, the console device provides asynchronous serial driver semantics so that, in conjunction with the
STREAMS line discipline module ldterm(7M), it supports the termio(7I) terminal interface.
SEE ALSO
syslog(3C), termios(3C), ldterm(7M), termio(7I), msglog(7D), wscons(7D)
NOTES
In contrast to pre-SunOS 5.0 releases, it is no longer possible to redirect I/O intended for /dev/console to some other device. Instead,
redirection now applies to the workstation console device using a revised programming interface (see wscons(7D)). Since the system console
is normally configured to be the work station console, the overall effect is largely unchanged from previous releases.
See wscons(7D) for detailed descriptions of control sequence syntax, ANSI control functions, control character functions and escape
sequence functions.
