You should be able to use the predefined template #1. So you use AT&F1, set
your dte speed at 115.2K and away you go. I have verified this with both
Sportster and Courier products. For use with other modems, you will have to
dig through the Robotics manual, determine the template definition, and do a
stare and compare with the other modems command set. Once you find the like
commands, use that string. I used the raw string until I dug through the
manual on my quest for truth, and discovered it was a subset of AT&F1, I
started using it and have had no problems to date.
WRT the throughput issue, I have found that 4k/s is about all you will get
over a PPP dial up to an ISP. There are a lot of issues involved in
maximizing throughput, most of which are completely out of your control. A
work around which will give you rather snappy file transfers follows.
Most ISPs give you a shell account, so telnet into the designated server,
use ftp to "get" the file into your shell account (make sure you have enough
headroom in your account if the file is large, otherwise when you reach the
ceiling the server will abort the ftp session). After the file is on your
home server you can ftp "get" the file to your workstation. Compare the
throughput of the 2 ftp sessions and you will be surprised. Instead of using
an ftp session to get the file from the home server, use zmodem (hopefully
your isp will support it) and compare the transfer times.I beleive you will
find ftp + zmodem to be the fastest.
Good luck.
