notes to the serial port. But since there’s no modem there, the string gets put after the “login:” prompt.
If this string is mostly capital letters, the getty program (which runs login) at the other PC may
think that your terminal has only capital letters and try to use only capital letters. To avoid this,
configure the modem init strings sent by minicom to null (erase the init strings).
The terminal emulator “Procomm” (which is from Dos), can be used on a Linux PC if you run
dosemu to emulate Dos. For details see: http://solarflow.dyndns.org/pcplus/.
There’s a specialized Linux distribution: Serial Terminal Linux. It will turn a PC to into a
minicom-like terminal. It’s small (fits on a floppy) and will not let you use the PC for any other
purpose (when it’s running). It will let you have more than one session running (similar to virtual
terminals), one for each serial port you have.
TERM (non-free commercial software from Century Software) Terminal Emulator can emulate
Wyse60, 50; VT 220, 102, 100, 52: TV950, 925, 912; PCTERM; ANSI; IBM3101; ADM-1l; WANG
2110. Block mode is available for IBM and Wyse. It runs on a Linux PC.

make a non-Linux pc a terminal

Emulators exist which run on non-Linux PCs. They permit you to use a non-Linux-PC as a
terminal connected to a Linux-PC. Under DOS there is telix and procomm. Windows comes with
“HyperTerminal” (formerly simply called “Terminal” in Windows 3.x and DOS). Competing with
this is “HyperTerminal Private Edition” http://www.hilgraeve.com/htpe/index.html which is
non-free to business. It can emulate vt-220. The Windows “terminals” are intended for calling out
with a modem but they should also work as directly connected terminals?? Turbosoft’s TTWin
can emulate over 80 different terminals under Windows. See http://www.ttwin.com/ or http://
www.turbosoft.com.au/ (Australia). See also Reflection
For the Mac Computer there is emulation by Carnation Software http://www.carnationsoftware.
com/carnation/HT.Carn.Home.html
One place to check terminal emulation products is Shuford’s site, but it seems to lists old products
(which may still work OK). The fact that most only run under DOS (and not Windows) indicates
that this info is dated. See http://www.cs.utk.edu/~shuford/terminal/term_emulator_products.

WITH the Central and State Governments stepping up efforts to reach out e-governance
applications for the common man to bridge the digital divide, various Linux-based
applications are gaining momentum and Red Hat is on the roll, according to Mr Sachin
Dabir, Head-Enterprise Sales, Red Hat India.
Mr Dabir told Business Line that the Linux operating system and Advanced Server were
being supported by some of the world’s top enterprises, software and hardware vendors,
offering a range of infrastructure solutions at attractive price points.

systems.
