Narrative:
We were cleared for takeoff on runway 36R with a turn to 345 degrees after takeoff. First officer was making the takeoff. At lift-off I noticed a commuter rotating with us off runway 36L. We were slightly above and accelerating past the other aircraft. The first officer started the turn at 500 ft, but the commuter was not yet turning. I told the first officer to turn back to runway heading. We then went IMC. Very soon we got a TA and then an RA with the comments to monitor vertical speed. We then switched to departure control on 125.12. I informed them of what happened and requested a heading and was given a heading of 350 degrees. We then proceeded on course without further incident.

Title: ACR AT DFW DEPARTING WITH CLRNC TO TURN L OBSERVES COMMUTER LIFTING ABOUT THE SAME TIME ON THE L SIDE. ENTERING IMC CONDITIONS, PLT MAINTAINS RWY HEADING BUT RECEIVES TCASII TA THEN RA.
Narrative: WE WERE CLRED FOR TKOF ON RWY 36R WITH A TURN TO 345 DEGS AFTER TKOF. FO WAS MAKING THE TKOF. AT LIFT-OFF I NOTICED A COMMUTER ROTATING WITH US OFF RWY 36L. WE WERE SLIGHTLY ABOVE AND ACCELERATING PAST THE OTHER ACFT. THE FO STARTED THE TURN AT 500 FT, BUT THE COMMUTER WAS NOT YET TURNING. I TOLD THE FO TO TURN BACK TO RWY HEADING. WE THEN WENT IMC. VERY SOON WE GOT A TA AND THEN AN RA WITH THE COMMENTS TO MONITOR VERT SPD. WE THEN SWITCHED TO DEP CTL ON 125.12. I INFORMED THEM OF WHAT HAPPENED AND REQUESTED A HEADING AND WAS GIVEN A HDG OF 350 DEGS. WE THEN PROCEEDED ON COURSE WITHOUT FURTHER INCIDENT.
