I have a 386DX 25Mhz with a USR Sportster modem and BSDI 2.0 (no patches)

I've tried baud rates of 38400 and 9600 with absolutely no difference in 
results.

When I use tip, there are no data errors and everything works fine.

When I attempt to establish a PPP connection, I cannot sync the modem.  By 
running ktrace on the PPP process, I can see that the "ATE1\r" is being 
written, but the data being echoed back is "T1".

If I modified tip/aculib/hayes.c (lazycmd) so that there is a pause between 
each of the characters in the command (I set this for 10ms), then the ATE1 
command worked fine, but the program stalled on the ATV1, so I patched
sendcmd the same way and got farther.  

Conclusion: the modem likes pauses between each of the characters in a command
string.

Has anyone else experienced this? Any other comments?
USR is popular these days somebody else should have been here first.
