Hello Everyone: I need to write a Terminal Emulation Program. The problem I am having is this I have seen many people ask about serial port processing. I downloaded a ZIP file called E-TERM.ZIP, I thought I could get a clue on how to handle input/output with serial ports, but when I tried all 3 of the e-term programs, I set them up to run on COM1 at 19200 8n1. The results of this is that input from the serial port is losing data. Any HELP would be appreciated, otherwise I quess I'll have to try and figure it out myself, just thought someone could save me some time. Many TIA Later: + + + Rev.

There are several available on the net,;search for BNU, which seems to work and have pretty good instructions. Irv

Hello Ferlin, Most likely you will lose data over 9600 baud with E-Term. This is not the programs fault but with DOS. Writing programs to send data over 9600 baud is no problem, recieving them however is. You have a couple of options available to you: 1. Write an interupt service routine which will act as a reciever and shuffle the characters into a buffer as they come in. Then peek them out of the buffer. 2. Get a FOSSIL driver and write a program for it (much easier) I recommend BNU or X00. If you want them I have a simple FOSSIL terminal program and an include file for accessing FOSSIL drivers. If you would like a copy please email me at blackdog at cdc.net Regards, Greg Harris HHS -----Original Message----- From: Ferlin Scarborough <ferlin at SANDW.NET> To: EUPHORIA at LISTSERV.MUOHIO.EDU <EUPHORIA at LISTSERV.MUOHIO.EDU> Date: Thursday, June 18, 1998 8:58 PM Subject: Terminal Emulation > Hello Everyone: > > I need to write a Terminal Emulation Program.
