[comp.sys.ibm.pc] How to switch PC screen between 40 to 80 columns

francis@proxftl.UUCP (Francis H. Yu) (10/24/88)

Could any body tell me how to switch PC's screen between 40 to 80 columns using
some assembly of C codes? Is there a hardware register to set?

Please send me email. I don't regularly read this group. Thanks in advance.
