I had an issue with dropping bytes when reading one character at a time. Reading a string with the length according to LOC() function seemed to solve the problem. This is what my routine looks like: ff1=freefile open com "COM3:230400,n,8,1,cs0,cd0,ds0,rs" as #ff1 a102: sleep 20 while loc(ff1)>0 k=input$(loc(ff1),ff1) print k; wend goto a102 There is an argument that can be passed in the Open Com statement to specify a buffer size. Is it supported in DOS? Maybe I will have to whip out FB DOS compiler and experiment. BTW, I'm not sure why you are adding For Random, or what that would even mean in this context. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
