This article is from the Hangul & Internet in Korea FAQ, by Jungshik Shin jshin@minerva.cis.yale.edu with numerous contributions by others.
There are now 5 nationwide on-line service providers in Korea, HiTel,
Chollian MagicCall, Nowcom, PosServe, and UniTel. All of them offer
outbounding service to the Net. Besides, Chollian MagicCall, Nowcom, HiTel
and UniTel allow in-bound service from the Net by telnet/rlogin.
To access Chollian Magicall, telnet/rlogin to chollian.dacom.co.kr. For
Nowcom, telnet/rlogin to nowcom.co.kr and telnet/rlogin to home.hitel.net or
home.hitel.net for HiTel. For UniTel, telnet/rlogin to uniwin.unitel.co.kr.
You may also access UniTel with UniWin, the emulator made for UniTel access
under MS-Windows.
When telneting to these on-line services, 8bit clean telnet/rlogin and 8bit
clean terminal set up are to be used to enter Hangul. See Subject 16 for
details.
To transfer files to and from these services, you need a telnet client to
support file transfer protocol like zmodem and kermit. Some telnet clients
for MS-Windows/DOS including Netterm, Kermit for Windows95 and MS-Kermit
support either Zmodem or Kermit and for Unix, C-Kermit has built-in Kermit
support. Telnet from BSD 4.2 was modified(and named ztelnet) to enable
zmodem file transfer by ?? at KAIST and is available in /pub/hangul/network
at CAIR archive and its mirrors. It's compiled clean in Sun OS 4.x, but not
in other Unixen because it's based on old BSD source dating back to late
80's when most current flavors of Unix didn't exist. Sun OS 4.x binary,
however, seems to work with Solari 2.4. Linux binary was made by Park,
Myeong Seok at pms@romance.kaist.ac.kr and is available at
ftp://romance.kaist.ac.kr. Kang,Kilsang at pushnpop@chains.or.kr modified
SSL-MZtelnet-0.9.1 to support Hangul and Zmodem file transfer and put the
source (SSL-MZtelnet-0.9.1+zh) and Solaris 2.x binaries at
ftp://biko.chains.or.kr/incoming. This should be more easily compiled on
most Unix than the original ztelnet.
Mac users may try 5pm term, telnet client/terminal emulator with built-in
zmodem from Whitepine at http://www.wpine.com. Also, an extension,TCPserial
may be of interest to Mac users who want to transfer files from on-line
services in Korea. It's available at Info-Mac archive(
ftp://sumex-aim.stanford.edu or http://hyperarchive.lcs.mit.edu) In
addition, Hangul NiftyZtelnet 0.5 by
Kim,Jeong-hyun(jhkim@salmosa.kaist.ac.kr) has support for Zmodem
download(See Subject 18)
