Subject: IBM interupt handler for PS2
Newsgroups: comp.sys.ibm.pc

Netters 
	I am trying to write an interupt driven I/O handler on the IBM
PS 2. I am replacing the interupt vector OB and OC with hooks to my
routine for interupts. The address I am using are 3F8 and 2F8 for com1
and com2 resp. The interupt routine serial driver works fine with and
without loopback for IBM PC XT but fails with PS/2 or AT. Am I doing
something wrong in the vectors ? Any one have a simillar problem ? 
Any help will be greatly appreciated. Please mail replies to
{rutgers,cornell}!rochester!rit!ultb!sfm3166.

thanks
