I have been using AI-v0.9.5.0 AT Firmware.bin, and not downloaded any custom code.
what does busy p... stand for ? how to resolve it ? why does ESPlorer does have "Send Data" in tcp server Section ?

I found https://alselectro.wordpress.com/2015/05/13/wifi-module-esp8266-2-tcp-client-server-mode/ works for me

He demonstrated how to use ESP in server mode, i have done that. Issue is am not able to use ESP in tcp client mode.

- Sun May 21, 2017 5:51 pm #66166 What is the current mode of your ESP?

Possible mode values:

1. Station mode (client)
2. AP mode (host)
3. AP + Station mode (host and client)

Query:

Code: Select allAT+CWMODE?

Set:

Code: Select allAT+CWMODE=<required mode>

To use an ESP8266 as a client, it must be set to either 1 (client only) or 3 (client and AP/host).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
