I hope someone here can give me an answer?
I have a USR Sportster v34+ (33600). I have considerable difficulty making
this modem connect to the 3 BBS's which I mainly log on to. More often than
not, the modem will make 2 rings, and then drop out, and cycle to the next
number I have marked. The comms program, (Telix for Windows) will show the 
message "Last attempt busy". I sometimes have to try 10 to 15 times to make
a connection, yet on other occasions, it will pick up the BBS on the first
ring. As a test, I have dialled my mobile phone,(but not answered it), and
mostly, the modem will keep on ringing (as it should do?)
Just in case the message was correct (last attempt busy), I picked up another
handset, connected to the same line, after the dialling started, and listened.
The modem dropped the line after the 2nd ring, but as I had the line still
open with the other handset, the BBS picked up the call, and went into the
normal handshake mode, thus proving that the BBs was not busy, and thus (to my
mind), showing that the fault lay with the modem. As a further test, I tried
using QL2Fax, which came with the modem. Same result, drop out on the 2nd.
ring. 
	However, once I do connect, the modem performs flawlessly, giving me
a cps of on average 3100-3200. As regards receiving calls on file transfer
from another modem, it works well, picking up the call on the 1st. ring and
transferring the info with no problems.
Before I forget, mine is an internal version, which when plugged in, fired up
straight off.
Hoping one of you whizzes out there can put your finger on my problem. 
NB. Don't get too technical with an answer, as I am easily lost .
