Ok, I never thought of that, so it prompted me to get the manual out
once again for the remote machine's modem.
I found this little section that I must have overlooked before. It
states this modem is capable of data communications at rates of:
300,1200,2400,4800,9600,14400,19200,28800,38400,57600 and 115200 bps and
to make sure the com port baud rate settings are set to one of those
speeds.
Now the communications software is a mailer, FrontDoor, and there are
errorlevels set up for 31200 and 33600, would this cause a problem??
I usually get connects at 31200 but sometimes 33600. The 31200 connect
is usually pretty zippy but the 33600 is "usually" slightly choppy.
There are rare occasions it connects at 28800 but when that happens, I
get ascii screens and some garbage.
The com port is locked at 38400 using a fossil driver.
Since the com port is locked does the fallback connect rates really
matter or would it be giving me my problem with slow uploads?
 
It seems like every time I try to figure out why a connect rate is the
way it is, or to try to solve a problem a user of the bbs is having with
connecting I confuse myself so much that I end up not knowing which way
is up.

If I can get it to work for me, it will solve any problems that anybody
else might be having also. The ONLY problem that I or anybody else is
having is when there is a file transfer TO the system but the transfers
FROM the system work very well and stable. Both modems in this case are
internal, both modems are made by the same manufacturer and both are US
Robotics clones. The modem on the bbs has fax and voice capability and
the other machine only has fax capability but both are supposed to be
33.6 modems. It seems odd to me though that the one with voice
capability's default configuration is called using AT&F0 and the modem
with only fax is called with AT&F1 to enable hardware flow control. They
are both plug and play but only the fax modem is being used on a machine
with Win95 and the voice modem is being used on a DOS machine with no
multitasking at all.
 
Anyway...I am going to fiddle with the voice capable modem again since I
feel fairly confident that the fax only modem on the Win95 machine
should be set correctly. If you have any more suggestions please feel
most welcome to air them :)
