- ; I2RV-6.ASM Racal-Vadic VA212PA or VA3451 special IMP overlay 06/11/87
- ;
- ;
- ; The Racal-Vadic option in IMP supports the 1200V, 2400V and 2400PA
- ; autodial models. The VA212PA and 3451 models require a somewhat dif-
- ; ferent routine. Essentially they require a CR after the 'D' for dial
- ; and two carriage returns after the phone number has been entered, the
- ; first to enter the number in the modem and the second to initiate the
- ; actual dialing routine. In addition, they do use "verbose" mode, not
- ; terse mode, so it is necessary to "catch the echo characters" before
- ; proceeding.
- ;
- ; The following overlay can be added after the normal overlay, although
- ; it makes no difference when it is added, really - assuming the normal
- ; overlay is set for 1200 bps maximum speed and Racal-Vadic protocol.

- ; 06/11/87 Increased the RV3451 abort time after dialing to 60 seconds
- ; as it can only pulse dial and is very slow. Other changes
- ; to improve autodialing with 3451.

- ; 06/01/87 Altered addresses for use with IMP245. Use I2VB-4.ASM with
- ; IMP244. - Irv Hoff
- ;
- ; 10/27/85 There is enough difference in the VA212PA and VA3451 to add
- ; equates to select between the two. The 3451 is much slower
- ; to execute commands and needs substantial extra delays. My
- ; thanks to Bond Shands for extensive 3451 testing. I could
- ; do the 212PA testing myself.
