1. Terminal Emulation

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:

Assuming you are using DOS,  you will need a fossil driver, which
talks to the ports using interrupts.
There are several available on the net,;search for BNU, which
seems to work and have pretty good instructions.

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
