I am writing a program (BBS) and would like to know what the registers:
Modem Status (IE COM1:&H3FE)
Line Status
Modem Control
Line Control
LSB (Least Significant Byte)
MSB (Most Significant Byte)
 
Also, what can I do using these registers besides monitoring the carrier.

alternative-The proton bomb.The proton bomb kills people, trees, and  
horses and destroys buildings and trucks.In short,the proton bomb will
eradicate anything larger than a fingernail clipping, except for      
kitchen cockroaches, which are stangely immune to its effects."
