We are software developers looking for a way to enhance a telenet vt220 
emulator (TNVT220 on TCP/IP) that runs on a PC in either DOS or windows. We 
wish to add in drivers to the TNVT220 emulator so it can communicate to local 
devices on the PC.  Our specific requirements are that we will be sending HEX 
codes from our host based application to TNVT220 on the PC. Upon receipt of 
the HEX codes, the TNVT220 will call linked in subroutines to communicate via 
software drivers to devices.  
 
Our application is a retail POS application, and has been host based, 
communicating to terminals with configured cash drawers, pole displays etc. We 
would like to utilize integrated DOS based cash registers such as NCR, etc. tied 
in over TCP/IP. These DOS based registers have their own software drivers that 
control cash drawers, pole display printers etc. Our application, being host 
based, sends HEX codes through auxiliary ports off of dumb terminals.  
 
What we are trying to accomplish, is to use a terminal emulator (TNVT220) that 
will capture the HEX codes and translate them to device driver calls on the DOS 
based register to print, open cash drawer etc. 
 
To accomplish this we need to get source code to a TNVT220 emulator under 
DOS (and associated libraries), so that we can link in NCR drivers (these are 
developed in Microsoft C) to operate this DOS based register. 
 
Does any body know where we can get reliable source for a TNVT220 emulator 
to accomplish our goals? We need to run this under Novell's LAN workplace. 
 
Any and all suggestion would be appreciated. 
 
Thanks.
