I have been trying to make my c64 talk/listen to the user port (device #2) while running the BASIC interpreter. The idea is to use c64 as a slave computer under the total control of a master computer, while taking advantage of all the convenient features provided by the BASIC. I was only marginally successful doing it the following way: 1) Open device #2. No problem here. 2) Poke 154,2. This sets the default output device to the user port. This actually worked, except that it switched the default output device back to the screen whenever a) numbered basic statements are entered b) there are error of any type also the echoed characters did not go to the user port. 3) Poke 153,2. Supposedly this should set the default input device to the user port, but the command always irreversably send the c64 into some unknown state. I will appreciate any pointer to the solution of this problem. Kaihu Chen uiucdcs!chen
