Timothy,

Put this is your varables section of your program:

[b]temp1    VAR     BYTE        ' subroutine work vars[/b]

Redefine your:

[b]SEROUTSXB SUB[/b]

to:

[b]SEROUTSXB SUB 1[/b]

Modify:

[b]SEROUTSXB:
  SEROUT TxPin, Baud, char
  RETURN[/b]

to:

[b]SEROUTSXB:
  temp1 = __PARAM1
  SEROUT TxPin, Baud, temp1
  RETURN[/b]

Now replace all of your:

[b]GOSUB SEROUTSXB[/b]

With

[b]SEROUTSXB 13        ' transmits a carrage return[/b]

 

It would be better to define carrage returns or whatever in your constants section like:

[b]Cr    CON    13        ' ASCII Carrage Return[/b]

This way dou dont have to assign char before you call you SUB 

If you look at some of Jon's examples, that use subroutines, you'll notice that he defines temp1 and others as work variables. These work varables get assigned by the __PARAMx Aliases, see "SX/B Online Help>Reference>Aliases>SX/B Variables"
