[net.micro.apple] Novation Apple-Cat modem problem

dina@ucbtopaz.CC.Berkeley.ARPA (01/06/85)

I have a two-year old apple //e with a Novation Apple-Cat 300 baud
modem.  The following problem has existed ever since I purchased the
system: 

If the system is booted up cold and I dial out,  a connection 
will always be established upon the first try.  However, when
booting up and attempting to dial out *after* using the apple
for more than a few minutes, a connection with the host will 
NOT be established, regardless of who or what is being dialed.
The time necessary to elapse before I can successfully dial out
and establish a connection again seems to equal the time the apple
was left on prior to dialing.

I sent the modem back to Novation earlier this year, and it was
returned "fixed" according to them.  However, the problem still
remains; the necessary elapse time was just reduced a little.	

Does anybody have any insight as to what this problem is caused
by (heat?) and what the cure might be?  
Thanks in advance,

Dina Street
