Help needed with using 'asy' with interrupts 9 & 10

[Mike Barnes]

Does anyone know what needs to be done to make interrupts on the second
PIC work with Jim Murray's Async device driver (under SYS/AT 2.3)?
Interrupts 3,4 and 5 work fine, but I run into a problem with
interrupts 9 and 10. What seems to happen is that the line opens fine,
but only the first character is sent and then the line hangs. I believe
the tables in 'asy_conf.h' are set up correctly and my 'asy' line in
'master' is:

asy	36,35,37,42	ocrwis	cot	asy	0	5	4

The exact same problem occurred when I used Microport's standard
'asy.o' driver. No other devices in my system use interrupts 9 or 10.
Am I forgetting to change something??
