I have uploaded a program called BiModem (version 1.14) which allows
modem users to do full duplex transfers, that is, be sending a file
while receiving.
<msdos.modem>
BIMOD114.ARC Bi-directional communications protocol
Requirements: - PC/XT,AT,386
- 100k of memory available
- DOS 2.0 and up
---the following is copied form the manual---
BiModem is a new communications protocol which allows simultaneous
bidirectional file transfers. Yes, BiModem can upload while
downloading. Imagine the time savings if you could upload with Zmodem
(tm) and YmodemG efficiencies while downloading at the same efficiency
at the same time. The applications for such a protocol are many, and I
will not try to cover them here. Everyone from occasional BBS users
to full time network managers will appreciate the advantages of
exploiting full duplex operations. Even for those with small and
moderate volumes of data to transfer, the time savings can be very
significant. Please do not expect a 50% decrease in your overall modem
transfer time. This can only be achieved when the same amount of
information is transmitted in both directions, and does not account
for the overhead of specifying the lists of files to download and
upload.
If that feature is not enough to get you really excited, how about the
ability to chat while the transfer is going on? Chatting, of course,
will impact your throughput, but since most of us are slow typists,
when compared to the speed of even a 1200 baud modem, the impact is
usually minimal.

This program should supercede an earlier version (<msdos.modem>BIMOD107.ARC)
already residing in the archives. Enjoy!
