setting up a modem on an Ultra5
Hi I had this on the expert unix forum, but nobody answered the I saw this forum which is more to what I am doing.
I was setting up a modem on an Ultra5 running 2.6. (yes I know, how quaint)
There are 15 systems that are interlinked but not accessible to the outside world.
This will end soon with new updated sun systems but until then the system needs to be accessed by the outside world. Hence the modem.
I was called in to help out and discovered that the serial port was not set up correctly I corrected this and then happened to look at the eeprom and the engineer that I was helping remarked that the two entries for the serial ports had not been there before. Because the Ultra 5 is used in a production environment it cannot be shut it down to look at the ok prompt (OBP).
When admintool serial is changed and you choose "Apply" does this update the eeprom? And is it written to the eeprom or will it default to what it was before once the ultra 5 has been rebooted?
Thanks

eep24c
EEP24C(1) General Commands Manual EEP24C(1)
NAME
eep24c - read and write 24Cxxx eeprom devices
SYNOPSIS
eep24c -d device [ -r[n] filename | -w[n] filename | -k[n] filename | -f[n] xx ]
DESCRIPTION
The command eep24c can be used to read and write 24Cxxx eeprom devices.
OPTIONS
The following options are available:
-d device
Specify the device type. To see a list of the supported devices, try -d help
-r filename
Read from eeprom and save to a file.
-w filename
Read from a file and write to eeprom. The addresses not specified in the input file will be filled with 00.
-k filename
Read from a file and write to eeprom. The addresses not specified in the input file will be kept with its previous values. (this
mode is twice slower. It reads whole memory to know previous values, then write whole memory)
-f XX Fills the whole eeprom with XX (XX is an hexadecimal value)
n Can be used to multiply clock time. If you have a long cable, you may use this option. Example: -r5 will read eeprom 5 times slower
(pulse width will be standard value multiplied by 5). Valid range for n is from 1 to 50. Default value is 1.
USAGE EXAMPLES
eep24c -d 24c04 -r file.hex
read eeprom, write to file.hex
eep24c -d 24c04 -r3 file.hex
read eeprom, write to file.hex, 3 times slower.
eep24c -d 24c04 -w file.hex
read file.hex and write to eeprom. All the bytes not found in file.hex will be written as 00.
eep24c -d 24c04 -k file.hex
read file.hex and write to eeprom. All the bytes not found in file.hex will remain unchanged.
eep24c -d 24c04 -f 7A
fill eeprom with 7A (hexadecimal).
INPUT AND OUTPUT FORMAT
Input and output file format is Intel Hexadecimal Object File Format
You can find this specification at
ftp://download.intel.com/support/processors/
i960/devtools/INTELHEX.PDF
Record types 00 and 01 are implemented in this version. In input lines, LF and CR+LF are accepted as newline markers. Output files are
generated with LF as a newline marker.
DEVICE SPECIFIC
If you are using Microchip 24*515, you must tie its pin A2 to VCC (needs a hardware modification, see device datasheet).
