Serial channel, RW 2.1 RAP, M96

Robot Controller
1

Installed Robware OS 2.1 RAP version, serial link and advanced options floppies aswell. Rapid successfully writes text/info into file, but doesn’t see serial io channels - takes sio1: as invalid filename, while flp1: shows green light. Tried using COM1 aswell.

Any ideas what I might be doing wrong?

VAR iodev inchannel ;
.
Open “flp1:” File:= "log.txt ", inchannel;
Write inchannel, “bandymas3”;
Close inchannel;

^^Success, got file in floppy

VAR iodev inchannel ;
.
Open “sio1:”, inchannelBin;
Write inchannel, “bandymas3”;
Close inchannel;

Gives error on Write - says my filename is invalid (as ANSI doesn’t allow “:” in filenames ), even though I want to open rs232 port here which is sio1 - same way i oppened flp1:. In parametters i see all 4 sio’s available, and RAP - also installed and configured.

Will be thankful in advance for any help.
