I am attempting to write a serial port driver which will take advantage of the GS serial buffering ability...however, I can't seem to get the advanced interface to accept the call. Currently, I am using the routine/calls described below... LDA #${low byte of pointer} LDX #${middle byte} LDY #${bank byte} JSR $C214 {the address of the advanced interface...} The address pointed to contains this... $04 {#of parameters + 1 for the error + 1 for the command} $12 {Command for set InBuff} $0000 {error word} $00006000 {my input buffer address} $03FF {the length of the buffer} In reality, I'm also storing #$C2 in $7f8 and $CFFF, but that's not it... No matter what I try, the computer hangs...Any hints? Les Barstow a.k.a. Phoenix LMB7421@RITVAX.BITNET ..rutgers!rochester!ritcv!ultb!ritvax!lmb7421.UUCP 292 Kimball Dr. Rochester, NY 14623
