I still can't get Wordstar 4 to print anything, it just hangs. I don't know what it could be doing wrong, the LST: device isn't that hard to use....
Suspected a QP/M bug but ws4 also hangs from my older zcpr2 boot disks. ATM I don't have a vanilla cpm boot disk where LPT: (aka LST:) is set to 4800 baud.
