Previous Command
We have a Solaris Server and I am acessing it through telnet to run various commands for my data validation like GREP, SED, AWK etc.
My requirement is how do i use the previous command that was executed. I tried the option 'ESC' and then 'k'. It displays the characters like '^[[A' etc. How do I get my previous command in this case. Pls note I am using Microsoft Telnet to access the server.
I use to get it previously when I was working on AIX Server. But, I was using a unix client called 'X-Thin Pro'. Is it not possible with Telnet??

tels(7) Miscellaneous Information Manual tels(7)
NAME
tels, telm - STREAMS Telnet slave (pseudo-terminal) driver, STREAMS Telnet master driver (used by telnetd only), respectively
SYNOPSIS
DESCRIPTION
A Telnet pseudo-terminal consists of a tightly-coupled pair of character devices, called the master device and slave device. The master
and slave device drivers work together to provide a Telnet connection on the server side where the master provides a connection to and the
slave provides a terminal device special file access for the Telnet application processes, as depicted below:
--------------------------
| Pseudo terminal functions|
Application <--> |--------------------------| <--> telnetd
Processes | Slave | Master |
| (tels) | (telm) |
--------------------------
The slave driver, with (STREAMS pty emulation module) and (STREAMS line discipline module) pushed on top (not shown for simplicity), pro-
vides a terminal interface as described in termio(7). Whereas devices that provide the terminal interface described in termio(7) have a
hardware device behind them; in contrast, the slave device has manipulating it through the master side of the Telnet pseudo terminal.
There are no nodes in the file system for each individual master device. Rather, the master driver is set up as a STREAMS clone(7) driver
with its major device number set to the major for the clone driver and its minor device number set to the major for the driver. The master
driver is opened by telnetd using the open(2) system call with as the device file parameter. The clone open finds the next available minor
number for the master device. The master device is available only if it and its corresponding slave device are not already opened.
In order to use the STREAMS Telnet subsystem, a node for the master driver and N number of Telnet slave devices must be installed.
The number of slave devices is set by a kernel tunable parameter called This can be modified using SAM; its default and minimum value is
60. The value of is the upper limit of the number of telnet sessions that can be opened.
Multiple opens are allowed on the Telnet slave device.
The master and slave drivers pass all STREAMS messages to their adjacent drivers. When the connection is closed from the Telnet client
side, an message is sent to the corresponding slave device which will render that slave device unusable. The process on the slave side
gets the errno when attempting a write(2) system call to the slave device file but it will be able to read any data remaining in the slave
stream. Finally, when all the data has been read, the read(2) system call will return 0, indicating that the slave can no longer be used.
