Hangup in modem hangs up IRIX (or at least slows it down)

I configured a modem to be available for both dial in/out. 

If I kill the connection by just interrupting the line on the client side who
dialed in to the indigo, the connection breaks but the process of the 
client does not. This causes the console to throw out a dozen 
bufcall: could not allocate stream event
messages, and then, hundreds of 
select: Resource temporarily unavailable
messages which go away only if I kill the residual process. This means 
that the poor indigo slows down so much that normal editing is a pain if 
the problem occurs. 


The gettydefs file reads: 
bx_38400# B38400 # B38400 SANE TAB3 HUPCL  #\nlogin: #du_9600

The inittab file: 
t2:23:respawn:/usr/lib/uucp/uugetty -N -i wait,conn ttyf2 bx_38400 vt100 LDISC1 

The wait entry in the Dialers file: 
wait =,-, "" \dATZ\r\c OK \dAT&B1\r\c OK \dATS0=4\r\c OK
i.e., I do a modem reset (Z), a baud rate setting (&B1), and set the answer 
after the 4th ring (S0=4). Then I wait for the conn: 
conn    =W=,    CONNECT


The modem connects fine, and has very good throughput, in 14400 bps with 
error correction and compression. the 38400 bps to ttyf2 are there because 
in the end I intend to run SLIP on it. 

Any hints, suggestions and pointers appreciated. 

Regards 
Reinhard
